Asymmetric inductive effects have been measured on the Diels-Alder reaction of dimethyl fumarate with o-quinodimethane bearing a chiral u-alkoxy group. The chiral substituents used were f-phenylethoxy, 2-(1-phenyl)propoxy, 1-(2\_phenyl)propoxy, 2-(4-phenyljbutoxy and l-cyclohexylethoxy. The greatest
7,8-Bis(dibromomethyl)-3-bromo-2,4-diphenyl-3H-benzodiazepine 1 was used as a precursor for the benzodiazepine o-quinodimethane 2, which was trapped by in situ reactions with dienophiles.
