Convenient Preparation of Allylic and Vinylic Ketones from Carboxylic Esters and Grignard Reagents. Synthesis of ar-Turmerone

A method was established for the synthesis of long chain ketones by reactions of 3, 4-unsaturated carboxylic esters with alkyl and alkenyl Grignard reagents. Grignard reaction of ethyl (E) -3-hexenoate (1b) with n-pentylmagnesium bromide (2a) gave 3-dodecen-6-one (3b) and 6-n-pentyl-3-dodecen-6-ol (...
