Use of the Wadsworth-Emmons reaction for preparing hindered vinyl ethers and related 1,2-dioxetanes

Roeschlaub, Carl A.,Sammes, Peter G.

, p. 2243 - 2248 (2007/10/03)

Arylaldehyde acctals can be reacted with trimethyl phosphite to produce the corresponding dimethyl α-methoxy-benzylphosphonates, themselves used in a Wadsworth-Emmons reaction with adamantanone to produce hindered methyl vinyl ethers. These vinyl ethers are useful in the preparation of chemiluminescent 1,2-dioxetanes. The scope of the reaction has been explored.
