The asymmetric synthesis of novel non-proteinogenic β-heterocyclic α-amino acids via the diastereoselective conjugate addition of heterocyclic nucleophiles to the dehydroalanine moiety of chiral Ni(II) complexes has been studied. The complexes were

New chiral NiII complex of the dehydroaminobutanoic acid Schiff base with (S)‐N‐(2‐benzoylphenyl)‐1‐(3,4‐dichlorbenzyl)pyrrolidyl‐2‐carboxamide (CPB) was synthesized and tested as electrophile component in the asymmetric Michael addit

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

It was shown that dialkylpropargyl/3-(p-chlorophenyl)-2,3-dichloroallyl/ammonium salts in an aqueous alkali medium undergo cyclization-dehydrochlorination to give chlorine-containing benzisoindolinium salts. When the ammonium salt contains simultaneo
