Abstract

Isotetronic acids are of great interest in agricultural and pharmacological research and occur in a number of natural products. This paper describes the first Claisen rearrangement of the O-allyl substituted isotetronic acids 2 under thermal conditions furnishing the β-allyl substituted isotetronic acid derivatives 3 in high yields.
