Abstract

Palladium-catalysed coupling of a vinylstannane or vinyl boronic acids with 5-iodo-1,4-bis(tosyl)-1,2,3,4-tetrahydro­pyridines yields 1,3-dienes. These participate in homo- and hetero-Diels-Alder reactions with unsaturated carbonyl compounds and with nitroso species generated in situ to give novel bicyclic compounds in a highly stereoselective fashion.
