摘要

Abstract The arylcyclopropanone methyl hemiacetals (aryl= C 6 H 5, p-ClC 6 H 4 and p-CH 3 C 6 H 4) are quantitatively isomerised by sodium methoxide or tert-amines to propionic esters. The ring fission is rapid and occurs exclusively at the C 1-C 2 position, leading to products derived from the most stable incipient carbanion.
