Abstract
Pyridine spirocycles play an important role in drug design and development. In this paper, a novel spirocyclic cyclopentapyridine compound was synthesized. Based on retrosynthesis analysis, commercially available 2-chloro-6-methoxypyridine was used as the starting material for the synthesis of the target molecule, accomplished through an eight-step reaction process. Particular emphasis was placed on the two most challenging steps: selective Negishi coupling and carbonyl reduction.
