Study of cyclic derivatives of 1,2-and 1,3-aminoalcohols as chiral catalysts in additions of diethylzinc to benzaldehyde
The enantioselectivity of the addition reactions of diethylzinc to benzaldehyde in the presence of cyclic derivatives of 1,2- and 1,3-aminoalcohols as catalysts has been studied.
Thermolysis of 3-(carbazol-3-yl)-2-azidopropenoates
Abstract Thermal cyclisation of 2-azido-3-(carbazol-3-yl)propenoic esters produces the 1,6-dihydropyrrolo[3,2- c ]carbazole and not the 1,9-dihydropyrrolo[2,3- b ]carbazole whereas, in the case of the 4-methylcarbazolyl derivative, the 1,9-dihydropyrrolo[2,3- b ]-carbazole is formed in preference to the alternative pyrido[4,3- c ]carbazole.
