Combining the regioselective room temperature/ambient pressure hydroformylation and a modification of the Doebner-Knoevenagel reaction allowed for the development of an efficient, one-pot procedure for the synthesis of (E)-α,β-unsaturated carboxylic acids. The reaction proceeds under mild conditions, tolerates a variety of functional groups and gives (E)-α,β-unsaturated carboxylic acids in good yields and with excellent regio-and stereocontrol. The practicability of this process has been demonstrated by a short protecting group-free synthesis of the queen honeybee pheromones 9-ODA[( E)-9-oxodec-2-enoic acid] and 9-HDA[( E)-9-hydroxydec-2-enoic acid].

Syntheses of various aromatic ethers of undecenyl bromide and thio ethers of undecenyl and undecanyl bromides with 2-benzothiazolethiol are described.The preparation of a few amides and their corresponding amines from undecenoic acid and different aromatic amines and benzyl amine are also reported.The bromo derivatives of a few amides have also been prepared.These compounds have been tested on common Indian red cotton bug for their juvenile hormone activity.
