5-formyl-δ—valerolactone : A useful synthon for the chiral synthesis of the vespa orientalis pheromone and the mosquito oviposition attractant pheromone
摘要:
A synthetic scheme starting from the reaction between the lithiated N-allyl-N-methyl-(bisdimethylamino)phosphoramide anion and the triflate derivative of (R)-(-)- or (S)-(+)-2,3-O-isopropylideneglycerol is described to prepare the key chiral synthon (R)-5- or (S)-5-formyl-delta-valerolactone that leads to the title compounds.
