This is especially important in medicinal chemistry and key to drug discovery. In this endeavor, as the vast majority of small-molecule drugs are of heterocyclic nature, the interplay of heterocycles with MCRs becomes significant [1]. Although the majority of work has been devoted to the synthesis of heterocyclic adducts from non-heterocyclic reactants [2, 3], we will focus, however, on the intrinsic reactivity of basic heterocycles as a source of synthetically useful MCRs (Scheme 1.1). This approach, still quite unexplored in the MCR context, is arguably a rich source of novel, complex scaffolds. There is a wide choice of commercially available heterocyclic inputs, which together with their often-exclusive reactivity make this perspective simple, conceptually attractive, and synthetically productive. In this chapter, we describe a representative selection of relevant results in the last six years, as the field has experienced impressive growth since our last revision [4], and an exhaustive account is out of scope. This update groups the highlighted processes according to the main reactivity modes defining the MCRs: concerted, radical, metal-catalyzed, carbonyl/imine, and isocyanide-based processes. Finally, a miscellany section is included to cluster those MCRs that do not clearly fit in the classification. Occasionally, some significant post-transformations and applications have been detailed.","PeriodicalId":281637,"journal":{"name":"Multicomponent Reactions towards Heterocycles","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124761208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
