[GRAPHICS]The diphenylmethyl amino protecting group can be efficiently removed by initial oxidation of the amine to an imine by 2,3-dichloro-5,6-dicyanobenzoquinone. The resulting imine can then be easily hydrolyzed under mildly acidic conditions. This method is particularly well suited for the preparation of alpha-amino phosphinates and alpha-amino phosphonates.
Synthesis of an α-Aminophosphonate Nucleoside as an Inhibitor of S-Adenosyl-l-Homocysteine Hydrolase
摘要:
A phosphonic acid analogue or S-adenosyl-L-homocysteine was prepared by a novel method and the epimeric mixture separated. Preliminary studies indicate that each epimer causes time-dependent inactivation of S-adenosyl-L-homocysteine hydrolase, however each presented distinct kinetic characteristics.
