Synthesis of haminol-A and haminol-B, polyenic alarm pheromones of Cephalaspidean molluscs
摘要:
Two stereocontrolled palladium-catalyzed cross-couplings of I-alkenyl boronic acids and aryl/alkenyl halides (the Suzuki-Miyaura reaction) are the key steps in an enantioselective approach to the polyene fragment of haminols A and B, alarm pheromones isolated from Haminoea navicula, a Cephalaspidean Opisthobranch mollusc. Chirality rested on the use of (S)-propylene oxide as the starting material. (C) 1998 Elsevier Science Ltd. All rights reserved.

Seven new 3-alkylpyridines, showing alarm pheromone activity, have been isolated from three Haminoea cephalaspidean molluscs: H. orteai, H. orbignyana and H. fusari. Structures were elucidated by spectral analysis; absolute stereochemistry was determined by applying Mosher's method.
