Abstract

Stereocomplementary Syntheses of 1,ω-Distannylated E,Z-Isomeric Conjugated Trienes, Tetraenes, and Pentaenes. -The synthesis is achieved by stereocontrolled C=C bond formation. All-E isomers are obtained by using Ramberg-Baecklund and mono-Z-configured polyenes by Julia olefination. -(BURGHART, J.; SORG, A.; BRUECKNER*, R.; Chem. Eur. J. 17 (2011) 23, 6469-6483, http://dx.
