Yamada, Sachiko,Suzuki, Hiromasa,Naito, Hiroyuki,Nomoto, Takashi,Takayama, Hiroaki
, p. 332 - 333 (1987)
A stereoselective synthesis of (E)-α0hydroxy -1,3-dienes, by thermal extrusion from adducts of 2,5-dihydrothiophene S,S-dioxide(1) with aldehydes and ketones, is presented and its extension to the synthesis of the dienone, (E)-tagetone, and of a 1,3,5-triene system, is illustrated.
ACYLATION OF 1,3-ALKADIENES BY ACYL FLUOROSULFONATES. STEREOSPECIFIC SYNTHESIS OF E AND Z ISOMERS OF CONJUGATED DIENONES

Acyl fluorosulfonates generated from acyl fluorides and SO3 permits acylation of butadiene and isoprene to give triconjugated dienones.This reaction proceeds stereospecifically and leads to E isomers of the corresponding dienones in the case of butadiene and Z isomers in the case of isoprene.
