ASYMETRIC SYNTHESIS X: THE HIGH ENANTIOSELECTIVE SYNTHESIS OF (R)-α-SUBSTITUTED BENZYLIC AMINES VIA THE MODIFIED (+)-CAMPHOR DERIVATIVE AS CHIRAL SYNTHON
A new chiral synthon-10-substituted (+)-camphor derivative (III) is synthesized.The alkylation of the (III) with a variety of alkylating agents gives the high enantioselectivity ranging from 72-100percent e.e..And the crystal structures of the (III) and (IV) are involved in explaining the results.
