ENE ADDUCTS OF N-SUBSTITUTED TRIAZOLINEDIONES IV. THE STEREOCHEMISTRY OF THE ADDUCTS OF 4-BENZYL-1,2,4-TRIAZOLINE-3,5-DIONE WITH THE N-PHENYLIMIDES OF CIS-4-CYCLOHEXENE-1,2-DICARBOXYLIC ACIDS

It was established by study of the PMR spectra of the ene adducts of 4-benzyl-1,2,4-triazoline-3,5-dione with N-phenyl-cis-4-cyclohexene-1,2-dicarboximide and its cis,cis-3-methyl and cis-4-methyl derivatives that the realization of the half-chair, distorted boat, and chair conformations in the six-membered carbon skeleton of the adducts is controlled by the presence of the methyl group at the allylic sp2 and sp3 carbon atom of the cyclohexene ring in the initial imides.
