l-ProT catalyzed highly regioselective N-alkoxyalkylation of purine rings with vinyl ethers
摘要:
An efficient and regioselective synthesis of N-9 alkoxyalkylated purine nucleoside derivatives was achieved via the N-alkoxyalkylation of purine rings with vinyl ethers catalyzed by L-ProT. The advantages of this protocol include good to excellent yield, mild reaction condition, and simple manipulation. A plausible mechanism for the transformation was given. (C) 2014 Jian-Jun Li.

Antimycobacterial Agents. 1. Thio Analogues of Purine
摘要:
Thio analogues of purine, pyridine, and pyrimidine were prepared based on the initial activity screening of several analogues of these heterocycles against Mycobacterium tuberculosis (Mtb). Certain 6-thio-substituted purine analogues described herein showed moderate to good inhibitory activity. In particular, two purine analogues 9-(ethylcarboxymethyl)-6-(decylthio)9H-purine (20) and 9-(ethylcarboxymethyl)-6-(dodecylthio)-9H-purine (21) exhibited MIC values of 1.56 and 0.78 mug/mL respectively against the Mtb H(37)Rv strain. N-9-Substitution apparently enhances the antimycobacterial activity in the purine series described herein.
