Abstract: The unique availability of substituted cyclohexa-1,4-
and 1,3-dienes, notably enol ethers, from Birch reduction of anisoles,
permits many novel synthetic reactions of general utility. The total
synthesis of several natural products derived from polyketides have
been accomplished using a Diels�Alder and Alder�Rickert process. The
strategies of the synthesis are discussed.
