A highly efficient practical method for the synthesis of chiral polyhydroxy-(E,E)-1-chlorodienols and (E)-5-hydroxy enynes
摘要:
An efficient protocol for the synthesis of chiral polyhydroxy-(E, E)-1-chlorodienols and (E)-5-hydroxy enynes from chiral 4,5-epoxy trans allyl chlorides and 4,5-O-isopropylidene allyl chlorides is described by using stoichiometric amount of LiNH2 or LDA in HMPA : THF (1 : 5) useful in the synthesis of biologically active natural products.
