  Practical Synthesis of an Enantiomerically Pure trans-4,5-Disubstituted 2-Pyrrolidinone via Enzymatic Resolution. Preparation of the LTB₄ Inhibitor BIRZ-227

  摘要：

  A practical synthesis of the enantiomerically pure BIRZ-227 (1), a,LTB4 inhibitor, has been developed. The key steps include the effective synthesis of the trans-diarylpyrrolidinone (+/-)-8 and the enzymatic resolution of N-acetoxymethyl pyrrolidinone (+/-)-10 by immobilized Lipase Novozym 435. Reduction of pyrrolidinone (+)-8 with borane and subsequent coupling with chlorobenzoxazole 2 furnished BIRZ-227 in high enantiomeric purity (99% ee). The overall process described herein required no chromatographic separation and is amenable to the preparation of multikilogram quantities of the desired drug candidate in a cost-effective manner.

  1,3-Cycloaddition of an azaallyl anion with 4-methoxystyrene furnishes the corresponding racemic trans-pyrrolidine. Resolution of both enantiomers was accomplished by fractional crystallization with the inexpensive diacetone-2-keto-L-gulonic acid. The absolute stereochemistry was determined by single crystal X-ray analysis of the corresponding sulfonamide. (C) 1997 Elsevier Science Ltd.
