A New Construction of 2-Alkoxypyrans by an Acylation−Reductive Cyclization Sequence
摘要:
A new convergent synthetic approach to a pyran motif common to many naturally occurring structures is described. In this approach, two fragments are joined by esterification, and a subsequent intramolecular reductive cyclization affords the 2-hydroxypyran.
