Stereoselectivity in the Diels-Alder Reaction of Phenyl- and Oxy-Substituted o-Quinodimethanes

Phenyl-, methoxy-, and acetoxy-substituted o-quinodimethanes (o-QDM) have been added to dimethyl fumarate and maleate to determine the stereoselectivity of the addition reaction.The o-QDM's were generated from the corresponding 1,3-dihydrobenzothiophen

o-Quinodimethanes from 3,6-Dihydrobenzo-1,2-oxanthiin-2-oxides

A two step synthesis of 3,6-dihydrobenzo-1,2-oxanthiin-2-oxide 5a from o-tolualdehyde via the photochemically produced 1-hydroxy-1,3-dihydrobenzothiophene-2,2-dioxide is described.Analoguos syntheses of 3 and 6 substituted derivatives of the benzosu
