, p. 2735 - 2762 (2007/10/02)
A diastereoselective synthesis of a highly functionalized decalin fragment 61 of the insect antifeedant azadirachtin 1 is described.An intramolecular Diels-Alder reaction of triene 15 and subsequent intramolecular aldol reaction were employed to assemble

This paper describes a detailed analysis of the influence of various substituents on the stereochemical outcome of the intramolecular Diels-Alder cyclisation of a number of ether-linked trienes.In particular, the role of diene planarity in governing react
Chemistry of insect antifeedants from Azadirachta Indica (Part 10): Synthesis of a highly functionalised decalin fragment of azadirachtin
Kolb,Ley
, p. 6187 - 6190 (2007/10/02)
The synthesis of a highly functionalised decalin fragment (2) of the antifeedant azadirachtin (1) is described. A silyl group was employed to control the stereoselectivity of several key steps and to introduce C3 hydroxyl functionality. A novel ring contr
