摘要

Synthesis of 4′-substituted (halogeno, phenyl, ethynyl, and cyano) neplanocin A analogues was carried out. A cyclopentenol derivative having a vinylstannane structure was designed as key-intermediate in this study, which was prepared based on radical-mediated sulfur-extrusive stannylation. The resulting stannylated cyclopentenol 15 was successfully condensed with 6-chloropurine through the Mitsunobu reaction, leading to the carbocyclic ...
