A simple and convenient method for isoprenylation of carbonyl compounds and ethoxyacetylene using the titled new boron containing “isoprene C-5 synthon” and application of this efficient procedure to the synthesis of ipsenol and ipsdienol are described.

A novel class of odorants is described where the odor is associated with the interaction of two functional groups, one being an H-donor (AH function), and the other an H-acceptor (B function). Generally, odor occurs only if the distance between the two structural elements (AH/B system) is less than 3 Å. Bifunctional derivatives of the p-menthane and iridane series served as models for deriving this
