A NOVEL AND EFFICIENT ROUTE TO CHIRAL 2-SUBSTITUTED CARBOCYCLIC 5'-N-ETHYL-CARBOXAMIDO-ADENOSINE (C-NECA)
Chen, Jen,Grim, Michael,Rock, Caren,Chan, Kenneth
, p. 5543 - 5546 (2007/10/02)
A series of chiral 2-substituted-carbocyclic-NECA analogs was prepared in seven steps with an efficient resolution.The overall yield is good and can be applied to the other carbocyclic nucleosides.
