Given the versatility of nitrogen-doped organic molecules in natural products, pharmaceuticals, agrochemicals and materials, many such transformations have been conceived during the last 200 years. While the focus has shifted more and more to developing new catalysts rather than reagents to achieve this goal, over the last couple of years we have been intrigued by the possibility of inventing new ammonia equivalents which suit modern catalytic synthesis. We review herein our recent study triggered by this renewed interest in reagent design, which has led to the discovery and application of N-(fluorosulfonyl)carbamates as a new class of aminating reagents.","PeriodicalId":17123,"journal":{"name":"Journal of Synthetic Organic Chemistry Japan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135565175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MSPs are a kind of coordination polymers and obtained by complexation of metal ions with multitopic organic ligands. MSPs show EC properties in the film state, activated by the electrochemical redox of the metal ions. The EC changes are caused by the reversible appearance and disappearance of the metal-to-ligand charge transfer (MLCT) absorption in the metal complex moieties of MSPs. ECDs with MSPs have great potential for the future’s smart window applications and spreading.","PeriodicalId":17123,"journal":{"name":"Journal of Synthetic Organic Chemistry Japan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135565171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the past three decades, many methods to convert C-H bonds distal from functional groups, which were generally considered inert, have been developed. These advances now enable selective peripheral functionalizations at a late-stage. The direct engagement of traditionally unreactive C-H bonds in reactions expands chemical space by reducing functional group interconversions. As such, C-H functionalization serves as a powerful tool in medicinal and agrocultural chemistry as well as in the total synthesis of natural products where diversification to a broad array of compounds from a common intermediate is often desired. In this Account, we detail the thought processes and design principles that relied on emerging methods for C-H functionalization to prepare a wide range of bridged, polycyclic, natural products in the cephalotane and longibornane families from a common intermediate in each case.","PeriodicalId":17123,"journal":{"name":"Journal of Synthetic Organic Chemistry Japan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135565160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although an array of synthetic strategies have been developed to construct both known and new PCA scaffolds in the past decades, flexible and expedient strategies for creating PCAs with differently sized rings embedded are rare. We describe herein our recent studies on the tandem oxidative ring expansion (TORE) strategy for the construction of structurally diverse PCAs involving intra- and intermolecular TORE reactions for hexagon-embedded PCAs, and intramolecular TORE reactions for O- or S-incorporated heptagon-embedded PCAs and octagon-embedded PCAs.","PeriodicalId":17123,"journal":{"name":"Journal of Synthetic Organic Chemistry Japan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135565164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typically, electrochemical reactions have been carried out using direct current (DC), where electrons flow in a single direction. In contrast, utilization of alternating current (AC) has been largely unexplored in synthetic electrochemistry despite its wide applications in our daily life. This could stem from a historical perception regarding the lack of unique reactivity/selectivity that would result from using such a waveform, as well as the absence of readily available instrumentation to remove the engineering barrier for mass adoption. A breakthrough in this area is the introduction of rapid alternating polarity (rAP), which alternates the polarity of an electrode in the millisecond timescale. This mode of current delivery, now implemented in the widely employed potentiostat, ElectraSyn2.0, enables access to unique reactivity and selectivity in organic synthesis that are challenging or currently impossible to achieve by any known method (chemical or electrochemical). The remarkable chemoselectivity and simplicity of rAP open new vistas in modern synthetic electrochemistry.","PeriodicalId":17123,"journal":{"name":"Journal of Synthetic Organic Chemistry Japan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135565161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
