STEREOSELECTIVE SYNTHESIS OF METHOXY SUBSTITUTED 2,3-DIBENZYL-γ-BUTYROLACTONES USING ORGANIC PHOSPHONATES AS INTERMEDIATES

A stereoselective, short and convergent synthesis of methoxy substituted 2,3-dibenzyl-γ-butyrolactones was developed using organic phosphonates as key intermediates.

Stereoselective synthesis of methoxy substituted 2,3-dibenzylbutyrolactones via organic phosphonates

A highly convergent, short and stereoselective synthesis of a series of methoxy substituted 2,3-dibenzylbutyrolactones was achieved using a Horner-Wadsworth-Emmons (HWE) reaction as the key step in overall yields above 32%.
