The in situ synthesis and subsequent reactions of macrocylic imine 2 are reported. The imine was trapped with cyanotrimethylsilane to give α-amino nitrile aza-[13]-macrodiolides in a 1:1 ratio of diastereomers. A crystal structure of the syn α-cyano nitrile diastereomer, 7a, provided insights into the lack of selectivity in reactions of 2 relative to macrocyclic alkene 1. Reactions to functionalize
报道了大环亚胺2的原位合成和随后的反应。用氰基三甲基硅烷捕获亚胺,以非对映异构体1:1比例得到α-氨基腈氮杂-[13]-大丁二醇。合成α-氰基腈非对映异构体7a的晶体结构提供了2相对于大环烯烃1的反应缺乏选择性的见解。还报道了使顺式非对映异构体7a官能化的反应。
