AMraet-The course of consecutive reactions comprising two reaction stages is calculated. An examination is made of the effect which the order of the two reactions has on the yields of intermediate and fmal products. A number of graphs are constructed showing the influence of time and reaction condi
Diastereofacial selectivities observed for Diels-Alder cycloadditions of achiral dienes with chiral vinyl sulfoxides are rationalized in terms of electrostatics. The "nucleophilic" diene adds to the electron-poor face of the "electrophilic" dienophile.
