سنتز 1، 3، 5، 7-تترا استیل-1، 3، 5، 7-تترا آزاسیکلواکتان (TAT) از طریق استیل‌دار کردن 3، 7-دی‌استیل-1، 3، 5، 7-تترا آزا بی‌سیکلو-[3.3.1]-نونان (DAPT)
In this study, a novel method to synthesis of 1,3,5,7-tetraacetyl octahydro-1,3,5,7-tetraazocine or 1,3,5,7-tetraacetyl-1,3,5,7-tetraazacyclooctane (TAT) was used through acetolysis of 3,7-diacetyl-1,3,5,7-tetraazabicyclo-[3.3.1]nonane (DAPT) with acetic anhydride in the presence of sodium acetate as catalyst. Optimized reaction conditions were obtained by changing temperature, time and startin...

In the title compound, C(25)H(25)N(3)O(4), the central pyrrolidine ring and the two pyrrolidine rings adopt twisted conformations, whereas the piperidine ring in the octa-hydro-indolizine fused ring system adopts a chair conformation. The indoline ring systems are almost perpendicular with respect to the mean plane of the octa-hydro-indolizine ring system, making dihedral angles of 84.4 (5) and...
متن کامل7-(tert-Butyldiphenylsilyloxy)-2,2-dimethyl-1-benzofuran-3(2H)-one
The title compound, C(26)H(28)O(3)Si, is an allylic oxidation product of the tert-but-yl(2,2-dimethyl-2,3-dihydro-benzo-furan-7-yl-oxy)diphenyl-silane with N-bromo-succinimide and 2,2'-azobis-isobutyronitrile. The nine-atom bicyclic system is almost planar, with an r.m.s deviation of 0.0123 (2) Å and a maximum deviation of 0.031 (2) Å for the O atom. In the crystal, the mol-ecules pile up along...

متن کاملMicrowave assisted synthesis of [4, 5-e] [1, 3, 4]thia- diazin-7-yl] hydrazine Derivatives
New pyrimido [4, 5-e] [1, 3, 4]thia- diazin-7-yl] hydrazines were synthesized via the cyclocondensation of alkyl-2-phenylhydrazinecarbodithioates as a binucleophile with 5-bromo-2,4-dichloro-6-methylpyrimidine as a bielectrophile , and replacement of C-7 chloro atom by hydrazine in ethanol as the solvent . This method has advantages over methods currently described in the literature for the con...
