5′′-(4-Methoxybenzylidene)-7′-(4-methoxyphenyl)-1′′-methyl-5′,6′,7′,7a’-tetrahydrodispiro[acenaphthene-1,5′-pyrrolo[1,2-c][1,3]thiazole-6′,3′′-piperidine]-2,4′′-dione
In the title compound, C(37)H(34)N(2)O(4)S, the piperidine ring adopts a half-chair conformation. The thia-zole ring adopts a slightly twisted envelope conformation and the pyrrole ring adopts an envelope conformation; in each case, the C atom linking the rings is the flap atom. An intra-molecular C-H⋯O inter-action is noted. The crystal structure is stabilized by C-H⋯O and C-H⋯π inter-actions.
متن کاملGold(III) chloride catalysed synthesis of 5-alkylidene-dihydrothiazoles.
A two step synthesis of dihydrothiazoles is presented. First, the previously unknown N-propargylic dithiocarboimidates are produced in good yields from easily available, cheap starting materials. The subsequent gold catalysed ring closure is fast and efficient, leading to dihydrothiazoles through a cascade of 5-exo-dig cyclisation and 1,3-alkyl migration. The yields range from 74% to 95%.
متن کاملSynthesis of Some Nitrogen Functional Derivatives of 5-substituted-6-azauracil as Biologically Active Compounds
3-Arylhydrazono-2,4-dioxo-4-phenylbutanoates have been prepared by the coupling of benzoylpyruvate with aryldiazonium chlorides. Reactions of the 3-arylhydrazono-2,4- dioxo-4-phenylbutanoates with 1-aminoguanidine, semicarbazide, and thiosemicarbazide gave 5-substituted 2-imino-6-azauracil (3a), 6-azauracil (3b), and 2-thio-6-azauracil (3c), respectively. The analytical data of these compounds ...
