Efficient, formal syntheses of aphanorphine and eptazocine are reported that involve epoxide cyclizations. The necessary chiral epoxides were prepared following treatment of diols prepared by Sharpless asymmetric osmylations of an alkene. The cyclizations formed a ring compound with the same enantiomeric purity as the starting epoxide.
据报道,涉及环氧化物环化的高效,正式的甲啡肽和庚唑碱合成。在处理通过烯烃的Sharpless不对称渗透作用制备的二醇之后,制备必要的手性环氧化物。环化形成具有与起始环氧化物相同的对映体纯度的环化合物。
