CHEMISTRY OF INSECT ANTIFEEDANTS FROM AZADIRACHTA INDICA (Part 3) REACTIONS ON THE C-22,23 ENOL ETHER DOUBLE BOND OF AZADIRACHTIN AND CONVERSION TO 22,23-DIHYDRO-23-&β-METHOXYAZADIRACHTIN.

Azadirachtin (1) can be converted to the natural product 22,23-dihydro-23β-methoxyazadirachtin (2) via selective bromomethoxylation of the C-22,23 enol ether double bond and tri-n-butyltin hydride reduction; the corresponding acetic acid adduct on pyrolysis affords (1) in high yield.The antifeedant effects of the addition compounds were assessed.
