Cyclopropylamines are versatile intermediates and products both in organic synthesis in general and for active substances in particular. Although the synthesis of the corresponding enantiomerically pure cyclopropylboronic esters had been established previously, the C–B to C–N transformation was elusive. A detailed study directed towards the synthesis of several enantiomerically pure cyclopropylamines
环丙胺是通用的中间体和产品,通常用于有机合成,尤其是用于活性物质。尽管之前已经建立了相应的对映体纯环丙基硼酸酯的合成,但 C-B 到 C-N 的转化是难以捉摸的。公开了针对几种对映体纯环丙胺合成的详细研究;反苯环丙胺[(1S,2R)-36]和已知的belactosin A中间体43都是通过使用三氟硼酸盐作为关键中间体获得的。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
