Traditional three-component Petasis methods normally use various catalysts under harsh conditions (high temperature, microwave, etc.) for long reaction times. In this study, we developed a green and highly efficient microdroplet method for accelerating the Petasis reaction, which obtain good yields without the need of any catalysts under mild reaction conditions. The Petasis reaction in microdroplets was suitable for a variety of salicylaldehydes, arylboronic acids and amines. The Petasis reaction in microdroplets was accelerated by approximately 4 orders of magnitude by comparing the measured rate constants in bulk. Further, a scaled-up amount of 0.8 g h<sup>−1</sup> was achieved for the Petasis reaction in microdroplets. This study supplies not only a high-efficiency and environment-friendly methodology to constructing aryl amines in organic community but also a useful derivatization strategy for highly sensitive mass spectrometric detection of arylboronic acids and aryl aldehydes.</p>","PeriodicalId":72192,"journal":{"name":"Analysis & sensing","volume":"3 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"109163378","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}

Bioresponsive contrast agents are the key to expanding the diagnostic potential of MRI by providing anatomical information and discerning biochemical activity. Recent developments in the field of responsive and gadolinium-based agents have resulted in novel complexes that can sense their chemical microenvironments and thus study various functional processes in the tissue. Herein, we discuss the design and use of Gd(III)-based and bioresponsive MRI contrast agents for specific biological markers such as Ca(II) and Zn(II) cations and zwitterionic amino acid neurotransmitters. Combining their basic physicochemical characteristics with aspects that should be considered for their use in vivo would achieve the desired sensing features and enable their applications in functional molecular imaging to visualize essential biological processes.</p>","PeriodicalId":72192,"journal":{"name":"Analysis & sensing","volume":"3 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"109170748","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}
