Asymmetric synthesis of phoenicol, ferrugineol and cruentol, aggregation pheromones of Rhynchophorus spp.
摘要:
Syntheses of phoenicol, ferrugineol, and cruentol, aggregation pheromones of Rhynchophorus palm weevils, have been achieved with an overall yield of 42, 40 and 41%, respectively (five steps), in high enantiomeric purity. (C) 1999 Elsevier Science Ltd. All rights reserved.

reagent for syn-selective aldolreactions has been developed based on the recent finding that the stereochemistry of the boron-mediatedaldolreaction of a carboxylic ester is controlled by the bulkiness of the alcohol moiety of the ester, by the proper choice of reagents, and by the enolization conditions. This readily available, inexpensive reagent has been utilized in studies directed towards the synthesis
