The13C NMR spectra of the initial ω-aryloxy chains and the final 16-and 17-aryloxyprostaglandins of the 11-deoxy series have been investigated, and stereochemical assignments have been made for the diastereomeric pairs. A weakening of the diastereotopic effects in the spectra of the 15- and 16-methyl-substituted 16- and 17-phenoxypropstaglandins to 0.1 ppm has been shown. 相似文献

A library of new (1,5,3-dithiazepan-3-yl)alkanoic acids was prepared by the multicomponent cyclocondensation of amino acids, formaldehyde, and 1,2-ethanedithiol in water at room temperature for 1 to 5 h in high yields. This green procedure offers several advantages such as an operational simplicity, no catalyst, and no production of hazardous materials. 相似文献

An efficient procedure has been developed for the synthesis of difficultly accessible 9,9′-(alkane-α,ω-diyl)bis[7-(diphenylmethylidene)bicyclo[4.2.1]nona-2,4-dienes] and 16,16′-(alkane-α,ω-diyl)bis(tricyclo-[9.4.1.02,10]hexa-2,12,14-trienes) in 55–84% yields by [6π + 2π]-cycloaddition of 7,7′-(alkane-α,ω-diyl)bis-(cyclohepta-1,3,5-trienes) to 1,1-diphenylpropa-1,2-diene and cyclonona-1,2-diene in the presence of the catalytic system Ti(acac)2Cl2–Et2AlCl. The structure of the isolated compounds has been reliably proved by modern spectral methods. 相似文献

One-pot synthesis of 2-[(hydroxy- and methoxyphenyl)methyl]butane-1,4-diols in an overall yield of 60–65% by cycloalumination of allylbenzenes (4-allyl-1-methoxybenzene, 4-allyl-1,2-dimethoxybenzene, 5-allyl-2-methoxyphenol, and 5-allyl-1,2,3-trimethoxybenzene) with triethylaluminum in the presence of Cp2ZrCl2 is reported for the first time. The developed procedure opens a new synthetic route to practically important β-substituted butane-1,4-diols that are precursors to dibenzylbutane lignans. 相似文献

Ozonides of higher perfluoroalkenes were prepared for the first time by ozonation of perfluorooct-1-and-2-enes in Freon-113. The structures of the resulting compounds were confirmed by13C NMR spectroscopy and GLC-mass spectrometry. 相似文献

Zirconium-catalyzed cycloalumination of cycloalkadiynes assisted by Et3Al, subsequent treatment of the in situ generated tricyclic dialuminum compounds with BrCH2OMe and finally cyclopropanation of the obtained dispiro cyclopropyl dimethylene macrocarbocycles with Et3Al-CH2I2 represents an efficient one-pot synthetic approach to prepare di- and tetraspiro cyclopropane-containing macrocarbocycles in very high yields. 相似文献
