An efficient method was developed for the asymmetric synthesis of (R)-S-(1,2,4-triazol-3-yl)cysteines by the addition of 3,4-disubstituted 1,2,4-triazole-5-thiols at the electrophilic C=C bond in a NiII complex of a Schiff base of dehydroalanine with

Methylphenylpropargyl-(3-phenylpropargyl)-ammonium bromide salts are cyclized almost quantitatively under base-catalysis conditions with the formation of 2-methyl-2-phenylbenz[f]isoindolinium bromide. The allyl analog is subject to rearrangement-deco

It has been shown that, under basic catalytic conditions, dimethylpropargylallyl-(1-allyl-3 phenylpropargyl)- and-(1-allyl-3-α-naphthylpropargyl)atnmoniutn salts undergo diene synthesis type intratnolecular cyclization to form condensed analogs of i
