Stereoselective synthesis of methoxy substituted 2,3-dibenzylbutyrolactones via organic phosphonates
Compagnone,Suarez
, p. 3041 - 3051 (1992)
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%.
