Dioxolanones as Synthetic Intermediates. Part 1. Synthesis of α-Keto Acids, α-Keto Aldehydes, and α-Ketols

2,2-Pentamethylene-1,3-dioxolan-4-one (10) has been elaborated to provide 5'-ylidene derivatives using a Wittig approach.This apparently novel class of compounds is subject to nucleophilic attack at the 4-position because of strain inherent in the 5-membered ring.Thus alkaline hydrolysis leads to the formation of α-keto acids; hydride reduction of dioxolanones incorporating conjugated aryl substituents using di-isobutylaluminium hydride leads to α-keto-aldehydes; the reaction of dioxolanone (15) with methylmagnesium iodide gave the α-ketol (40).
