route for preparing a versatile building block of isocyanides from primary amines is developed. Difluorocarbene, generated in situ from decarboxylation of chlorodifluoroacetate, reacts efficiently with primary amines to produce isocyanides. Various primary amines are well tolerated, including aryl, heteroaryl, benzyl, and alkyl amines, as well as amine residues in amino acids and peptides. Late-stage
开发了一种由伯胺制备通用的异氰酸酯结构单元的通用,方便和友好的途径。由氯二氟乙酸酯的脱羧作用而原位生成的二氟卡宾与伯胺有效反应生成异氰化物。各种伯胺具有良好的耐受性,包括芳基,杂芳基,苄基和烷基胺,以及氨基酸和肽中的胺残基。证明了生物活性胺的后期功能化,显示了其在药物设计和肽修饰中的实用能力。
