Methods have been developed for the N-alkylation of 1,2,4-dithiazolidine-3,5-dione 2 and the subsequent conversion of the N-alkylated derivatives into isocyanates 5. An extension of this methodology onto a solid-support is also reported. X-ray crystallographic analysis has been carried out on potassium 1,2,4-dithiazolidine-3,5-dione 3 for structural comparison with the parent heterocycle 2. 相似文献

Two new pyrrole 2,5-diamide clefts have been synthesized containing 4-nitrophenyl or 3,5-dinitrophenyl groups appended to the amide positions. The 3,5-dinitrophenyl derivative has been shown to deprotonate in the presence of fluoride, which in acetonitrile solution, gives rise to a deep blue colour. 相似文献

In the title compound, C23H22N4O, there is evidence for some bond fixation in the aryl component of the quinolinone unit. Pairs of molecules related by inversion are linked into R22(8) dimers by almost linear N—H...O hydrogen bonds, and dimers related by inversion are linked into chains by a single aromatic π–π stacking interaction. 相似文献

The salts, [Ph2B{OCH2CH2N(Me)(CH2)n}2][Ph4B3O3] (n = 4, 5), were prepared in moderate yields in MeOH solution from reaction of Ph2BOBPh2 with [N(CH2)n(Me)(CH2CH2OH)][OH] and PhB(OH)2 in a 1:2:4 ratio. The reactions also lead to Ph3B3O3. Both salts were characterized by NMR (1H, 13C, 11B) IR, and single-crystal XRD studies. The salts are comprised of cationic monoborates (zwitterionic, 2N+ and 1B−) and tetraphenylboroxinate anions. 相似文献

The synthesis of a range of cyclic guanidines via intramolecular ring opening of epoxides or iodocyclisation is reported. A preliminary investigation of the glycosidase inhibitory activity of these substances is also discussed. 相似文献

Valuable amino benzo[g,h,i]perylenes have been obtained through a one pot electrophilic aromatic substitution--Scholl reaction sequence. Novel molecular architectures combining 3D-o-carborane and planar amino benzo[g,h,i]perylene units are described. Photophysical properties of amino benzo[g,h,i]perylene and the carborane-appended derivatives are discussed. 相似文献
