摘要

Sharpless epoxidation of the readily available dienol 2, followed by regiospecific Summary: opening with Me CuLVBF3eEt20 yields, after protecting group manipulation, the monoprotected diol l& Swern oxidation gives the cyclic carbaminol J&a which is easily manipulated to a-cyano bxazolidinone x and thus, by literature methods, to the title compound. Using this procedure, good overall yield and high enantiomeric purity are ...
