  摘要：

  1-[(4-Methylphenyl)oxy]pyrrolidine-2,5-dione and 1-[(4-methylphenyl)oxy]piperidine-2,6-dione react in a Lossen-type reaction with primary alcohols in the presence of triethylamine to furnish corresponding N (alpha)-urethane-protected beta-alanine and gamma-aminopropionic acid (GABA), respectively, with excellent yields and purities, in an essentially "one-pot" procedure.

  esterase from Bacillus subtilis (BS2) allows the fast and selective removal of allyl, 2-chloroethyl, and 2,2,2-chloroethyl esters under mild conditions in high yields. In addition, BS2 easily hydrolyzes phenacyl esters, while the hydrolysis of sterically hindered diphenylmethyl esters is slow, requiring longer reaction time and higher enzyme/substrate ratio.

  来自枯草芽孢杆菌（BS2）的酯酶可在温和条件下以高收率快速选择性地除去烯丙基，2-氯乙基和2,2,2-氯乙基酯。此外，BS2容易水解苯甲酸酯，而位阻二苯甲基酯的水解缓慢，需要更长的反应时间和更高的酶/底物比。

  This paper reports the reaction of N-(phthalimidoyloxy)-3-phenylpropionate (2a) and -tosylate (6) with benzyl alcohol as a nucleophile to afford the products via Lossen-type rearrangement. To study the scope of this reaction mechanism, we also studied the reaction of several N-sulfonyloxyimide derivatives with benzyl alcohol under similar conditions and found that the same types of products were obtained
