  Interception of Secondary Amide Ylide with Sulfonamides: Catalyst-Controlled Synthesis ofN-Sulfonylamidine Derivatives

  摘要：

  A novel, secondary amide activation strategy has been developed through the in situ generation of ylides from amides and diazoacetates. Under the developed reaction conditions, Mn-catalyzed ylide formation and interception reaction by sulfonamide delivered a variety of N-sulfonylamidines. Notably, when highly active Zn(OTf)(2) was used as the catalyst, further N-H insertion products were obtained. In contrast with traditional methods, our amide activation strategy is distinguished by accessible starting material, inexpensive catalyst, and broad substrate scope.

  Amidine is a notable nitrogen‐containing structural motif found in bioactive natural products and pharmaceuticals. Herein, a novel rhodium(I)‐catalyzed tandem reaction of readily accessible azides with isonitriles and boronic acids via a carbodiimide intermediate is achieved. This protocol offers an alternative approach toward N‐sulfonyl‐, N‐acyl‐, and N‐ phosphoryl‐functionalized, as well as general

  idine是在生物活性天然产物和药物中发现的显着的含氮结构基序。本文中，通过碳二亚胺中间体实现了易于获得的叠氮化物与异腈和硼酸的新型铑（I）催化串联反应。该协议为N-磺酰基，N-酰基和N-磷酰基官能化以及具有广泛底物范围的常规N-芳基和N-烷基am提供了另一种方法。另外，当使用胺代替时，也可以合成官能化的胍。雌酮衍生的am和格列本脲生物等排体的完成进一步揭示了该策略的实用性。
