Abstract

Easily available material, β-(1-chlorovinyl)-β-propiolactone reacted with organocopper reagents to afford 4-chloro-3-alkenoic acids in high yields. The acids were easily transformed into two kinds of useful carboxylic acids such as 4-oxoalkanoic and 4-oxo-(E)-2- alkenoic acids leading to various natural products.
