Highly Enantioselective Synthesis of 3-Hydroxy-2-phenylpiperidine via the Sharpless AD-Reaction
摘要:
Asymmetric dihydroxylation (AD) of the silyl enol ether (3) provided after hydrolysis the hydroxy ketone (4). Subsequent hydrogenation yielded the title compound (1) as a diastereomeric mixture. The cis-isomer is an important building block for the synthesis of potent NK1 receptor antagonists.
