Studies Aimed at the Total Synthesis of Azadirachtin as an Insect Antifeedant

Abstract

Efficient construction of the respective right and left segments of azadirachtin is described. Furthermore, studies on the connection between both the segments are also mentioned; the Ireland‐Claisen rearrangement of Li‐enolate of the modelled ester with dichlorodimethylsilane in toluene afforded the desired limonoid framework stereoselectively in good yield.
