BENZYL ISOPROPENYL ETHER Usage And Synthesis

Uses

Benzyl Isopropenyl Ether is used for protecting group for compounds with multiple hydroxy groups; acetone enolate equivalent.

Synthesis

The first reported synthesis of the reagent was accomplished by the pyrolytic decarboxylation of β-benzyloxycrotonic acid^[1]. An alternate method for the preparation proceeds via dehydrohalogenation of 2-benzyloxy-1-chloropropane with potassium t-butoxide in DMSO (82% yield)^[2].
