The Birch reduction is unique, in synthetic approaches, due to the adaptable substitution patterns of the
substituted cyclohexa-1,4- and 1,3-dienes, particularly enol ethers. Birch reduction as a key and sometimes as the
only reduction tool has found several applications in total synthesis of several natural occurring compounds. This
name reduction is very important and quite useful for reduction of aromatic and none-aromatic moieties. It is particularly
useful in aromatic compounds due to its selectivity of reduction of certain double bonds, which are present
in one of the starting materials in multi-step total synthesis. It is also applicable when further reduction of nonaromatic
moieties as a part of natural product structures, is required. In this report, we try to highlight the applications
of this reaction as a key step in the total synthesis of natural products. It covers the applications of Birch reduction
in total synthesis of naturally occurring compounds from 2003 till date.
Keywords: Birch, reduction, natural product, total synthesis, anisol, alcohol, diene.
