PROCEDURE

实验过程

A mixture of pyroglutamate 8c (245.4 mg, 0.809 mmol) and Lawesson's reagent (164 mg, 0.404 mmol) in 6 mL benzene was stirred at reflux for 17 h, then concentrated. The crude product was purified by flash chromatography (0.5 to 1 to 1.5 to 2% MeOH/CHCl3) to afford 232 mg (90%) of the thiolactam 8d as a 2:1 mixture of diastereomers.
