  Stereoselective Synthesis of a Broad Spectrum 1β-Methylcarbapenem, J-114,870

  摘要：

  An ultra-broad spectrum carbapenem, J-114,870 (1), was synthesized from the corresponding C-2 side chain and 1 beta-methyl carbapenem enolphosphate. Synthesis of the C-2 side chain was accomplished by installation of the benzene part to (4R)-hydroxy-2-pyrrolidone 3, affording 2-phenylpyrrolidine 8a, and asymmetric Michael addition of chiral amine to alpha,beta-unsaturated ester derived from 8a.

  A (2R,4S)-trans-disubstituted pyrrolidine ring system was constructed by employing iodine-mediated oxidative cyclization of (1R)-N-[1-(4-bromophenyl)-3-butenyl]acetamide 3 as a key step. The resulting diastereomeric mixture of (2R)-2-aryl-4-acetoxypyrrolidine 4 was stereoselectively converted to the side-chain of a novel ultra-broad-spectrum carbapenem 1, via (2R,4R)-2-aryl-4-hydroxypyrrolidine 7.

  以(1R)-N-[1-(4-溴苯基)-3-丁烯基]乙酰胺3的碘介导氧化环化为关键步骤，构建了(2R,4S)-反式-二取代吡咯烷环体系。所得的(2R)-2-芳基-4-乙酰氧基吡咯烷4的非对映异构体混合物通过(2R,4R)-2-芳基-4-羟基吡咯烷立体选择性地转化为新型超广谱碳青霉烯1的侧链7.
