Trimethylsilyl-substituted dienophiles 1, 2, and 4 react with dienes 6-14 in 66-100percent yields to give β-trimethylsilyl-substituted carboxylic acids 15-25, some of which are hydrogenated to 26-31.These are decarboxylated-desilylated to cyclic olefins 35-47 by Non-Kolbe electrolysis in 45-91percent yields.The dienophiles 1, 2, and 4 are thus suitable acetylene equivalents for Diels-Alder reactions.
GENERAL APPLICABILITY OF Z-1,2-DIPHENYLSULFONYLETHYLENE AS ACETYLENE SYNTHON IN CYCLOADDITION REACTIONS: A TWO STEP SYNTHESIS OF TETRACYCLO2,4.03,7>NON-8-ENE AND TRICYCLO2,5>NONA-3,7-DIENE

Z-1,2-diphenylsulfonylethylene is shown to be a dienophile of general use since not only it cycloadds to conjugated 1,3-dienes but also to homo-conjugated double bonds and strained ?-bonds as those of norbornadiene and quadricyclane.The adducts can be red
