It was shown that 2,3,4,5-tetrahydro-1,4-benzoxazepines were cleaved at the N–C(5) bond under the action of activated alkynes in methanol, forming o-(methoxyethyl)- and o-(methoxybenzyl)-phenyl(aminoethyl) ethers. The cleavage rate depended on the

Fused benzodiazepines were found to react with activated alkynes to effect either vinylation of unsubstituted nitrogen atom or dealkylation of nitrogen and its further vinylation. For benzodiazepinones bearing lactam fragment, the reactions with alky

4-Aryl-1,2,3,6-tetrahydropyridinium quaternary salts which have a benzoylmethyl or ethoxycarbonylmethyl group on atom N-1 generate N-ylides when heated in the presence of NaH and they can rearrange in situ with contraction or expansion of the six-mem

Publikováno v: Russian Chemical Bulletin. 56:2323-2329

A reaction of substituted hexahydroazepino[4,3-b]-and-[3,4-b]indoles with activated alkynes was studied. A one-step method for the synthesis of isomeric hexahydroazonino[5,6-b]indoles different by positions of the double bond in the azonine ring was
