Preparation of α-methoxyallylphosphonates and their conversion into 2-methoxyalka-1,3-dienes
Abstract
A range of α-alkoxyphosphonates, including novel α-methoxyallyl phosphonates have been prepared from acetals. The latter have been used to provide an efficient and convenient synthesis of conjugated methoxy dienes, in which E-geometry predominates in the newly formed double bond but the geometry of the original allyl system is preserved.
