Kuchin // Helvetica Chimica Acta. - 2012. - Vol.95, №6. - С. 940-950 Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): 1H-IMIDAZOLES -- ASYMMETRIC OXIDATION -- X-RAY CRYSTALLOGRAPHY Аннотация: For the first time 2-(cis-caran-4-ylsulfanyl)-1H-imidazole, 1-methyl-2-(cis-caran-4-ylsulfanyl)-1H-imidazole, and 2-(cis-caran-4-ylsulfanyl)-1H-benzimidazole (carane=3,7,7-trimethylbicyclo[4.1.0]heptane) were synthesized, and the asymmetric oxidation of these compounds was also carried out. It was shown that oxidation by the Bolm system and the modified system of Sharpless lead to corresponding sulfoxides with de values of 91–100% |
