首次系统地研究了N-保护环烯丙基胺的m-CPBA环氧化反应的顺反立体选择性。单-N-保护的系统得到具有顺式立体化学的环氧化物(酰胺是比磺酰胺或氨基甲酸酯更好的顺式导向剂),而双-N-保护的系统得到反式环氧化物(TsNBoc保护得到完全的反式立体选择性)。[结构:见正文]
The first systematic study of the cis and trans stereoselectivity in the m-CPBA epoxidation of N-protected cyclic allylic amines has been completed. Mono-N-protected systems gave epoxides with cis stereochemistry (amides are better cis directors than sulfonamides or carbamates) whereas di-N-protected systems gave trans-epoxides (TsNBoc protection gave complete trans stereoselectivity).
