An Easy Procedure for the Preparation of 3-Methylidenetetrahydrofurans from Dimethyl Succinates

A new synthetic proceduree to obtain 3-methylidenetetrahydrofurans is described, in which the methylidene group is generated during the formation of the tetrahydrofuran ring. These are prepared by reduction of differently substituted dimethyl succinates obtained by Stobbe condensation.
