One-pot syntheses of 6-mercaptopurines (6MP) from 4,5-diamino-6-chloro-pyrimidines
摘要:
A one-pot synthesis of 6-mercaptopurines from 4,5-diamino-6-chloro-pyrimidine, an aldehyde and elemental sulfur is presented. The key advantage of this procedure is that it utilizes the in situ generated H2S to convert the chloro to a mercapto group. (C) 2004 Elsevier Ltd. All rights reserved.
6-Substituted purinyl piperazine derivatives and a method of synthesis for the derivatives are described. The 6-substituted purinyl piperazine derivatives are useful as cardiotonic agents and antiarrhythmic agents.
