A novel stereocontrolled synthesis of (z,z)-3,13-octadecadien-1-yl acetate, the sex pheromone of synanthedon species

Abstract Starting from 10-undecenoic acid, a stereocontrolled synthesis of (Z,Z)-3,13-octadecadien-1-yl acetate with high stereochemical purity was achieved by the use of Wittig-olefinations for the introductions of (Z)-double bonds.

Simple and Stereocontrolled Synthesis of an Optimal Isomeric Mixture of 3,13-Octadecadien-1-YL Acetates

Abstract A simple route has been developed for the preparation of the optimal isomeric mixture of 3,13-octadecadien-1-yl acetates /ODDA/ which is the active sex pheromone of many Synanthedon species. The stereocontrolled formation of double bonds have been achieved via Wittig reaction and subsequent reduction of C-C triple bond.

Preparation of Nitriles by the Modification of Mitsunobu-Wilk Procedure III Carbon Elongation of Hydroxy Esters

Abstract An efficient one-step procedure for the conversion of hydroxy esters into the corresponding nitrile esters using triphenylphosphine (PPh3)-diethyl azodicarboxylate (DEAD) in the presence of acetone cyanohydrin is described.

Preparation of Unsaturated Nitriles by the Modification of Mitsunobu-Wilk Procedure

Abstract An efficient one-step procedure for the conversion of unsaturated alcohols into the corresponding nitriles by the modification of Mitsunobu-Wilk reaction is described.

Preparation of Unsaturated Nitriles by the Modification of Mitsunobu-Wilk Procedure II Carbon Elongation of β-Acetylenic Alcohols

Abstract An efficient one-step procedure for the converison of β-acetylenic alcohols into the corresponding nitriles using triphenylphosphine (PPh3)-diethyl azodicarboxylate (DEAD) in the presence of acetone cyanohydrin is described.
