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

The thermal Claisenrearrangement of O-allyl substituted isotetronic acids 1 was successfully carried out within a glass microreactor operated with temperature at 150 °C and a flow rate of 1 mL/h. The strategy provides an efficient alternative way to β-allyl substituted isotetronic acid derivatives 2 in high yields with much accelerated reaction speed.
