The first example of an enolate accelerated Cope rearrangement is described along with its importance in the rearrangement of S-alkoxy-deca-1,3,7,9\_tetraenes. We recently introduced a macroexpansion method' for the synthesis of large ring compounds, exemplified by the conversion of 1 into 4(Scheme

Michael addition of the dienolate derived from 2-butenoic acid to 1,3-diphenylpropenone occurs through a 1,2-addition followed by a 13,31-sigmatropic rearrangement. oL,r-regioselectivity found for Michael addition to other styryl ketones depends on the s-ceric parameter of the substituents at the ca
