摘要

Described herein is the GaCl3-catalyzed lactonization of gamma-keto carboxylic acids in the presence of PhSiH3 leading to the direct preparation of gamma-lactone derivatives. This reducing system showed a relatively wide functional group tolerance.

机译：本文描述的是PHSIH3存在下γ-酮羧酸的GAC13催化的膀胱化，导致直接制备γ-内酯衍生物。该还原系统显示出相对宽的官能团耐受性。
