摘要：

Not much is known of the conformation of 4-hetero-substituted cyclohexene rings.1 Such a ring has been invoked as a conformational model, however, to explain the preferential formation of the less stable trans isomer of 2,6-diphenyltetrahydro-l-thiopyran-4-one (2) from reaction of dibenzylideneacetone (1) and sodium acetate in 90% aqueous ethanol saturated with hydrogen sulfide. © 1979, American Chemical Society.
