Rhodium catalyzed diastereoselective synthesis of 2,2,3,3-tetrasubstituted indolines from N-sulfonyl-1,2,3-triazoles and ortho-vinylanilines
An efficient diastereoselective rhodium catalyzed synthesis of indolines possessing two contiguous tetrasubstituted carbon centers has been achieved with good to excellent yields using ortho-vinylanilines and iminocarbenes derived from N-sulfonyl-1,2,3-triazoles. The reaction affords excellent cisdiastereoselectivity through the initial formation of a N-ylide followed by intramolecular trapping...
متن کاملRhodium-catalyzed transannulation of N-sulfonyl-1,2,3-triazoles and epoxides: regioselective synthesis of substituted 3,4-dihydro-2H-1,4-oxazines.
Rhodium-catalyzed transannulation of 1,2,3-triazoles and ring-opening reactions of epoxides is described. A number of 3,4-dihydro-2H-1,4-oxazines are obtained in moderate yields probably involving generation of α-imino rhodium(II) carbene species.
متن کاملCu(II)-catalyzed domino reaction of 2H-azirines with diazotetramic and diazotetronic acids. Synthesis of 2-substituted 2H-1,2,3-triazoles.
The Cu(II)-catalyzed addition of two molecules of a 3-aryl-2H-azirine to diazotetramic or diazotetronic acids proceeds as a domino reaction with the formation of 1,2,3-triazole derivatives with ortho-fused (pyrrolo[3,4-b]pyrrol or furo[3,4-b]pyrrol) and spiro-cyclic (1-oxa-4,7-diazaspiro[4.4]nonane or 1,7-dioxa-4-azaspiro[4.4]nonane) substituents at the N2 position. The disclosed reaction is a ...
متن کاملRhodium-Catalyzed Addition of Arylboronic Acids to N-Sulfonyl Aldimines
The addition of arylboronic acids, ArB(OH)2, to N-phenylsulfonyl aldimines, RCH=NSO2Ph (R=alkyl, aryl, 1-alkenyl), giving R(Ar)CHNHSO2Ph was carried out at 95 °C in the presence of a rhodium catalyst. [Rh(cod)(MeCN)2]BF4 (3 mol%) was found to be the best catalyst for aryl aldimines and Rh(acac)(coe)2/i-Pr3P for alkyl and 1-alkenyl aldimines. The analogous reactions of arylboronic esters, such a...
متن کاملBenign synthesis of N-aryl-3,10-dihydroacridin-1(2H)-one derivatives via ZnO nanoparticle-catalyzed Knoevenagel condensation/intramolecular enamination reaction
An efficient construction of 2-(N-arylamino)benzaldehydes and N-aryl-3,10-dihydroacridin-1(2H)-one derivatives starting from 2- hydroxybenzaldehydes has been developed. The synthesis of N-aryl-3,10-dihydroacridin-1(2H)-ones is based on the Knoevenagel condensation of dimedone to various 2-(N-arylamino)benzaldehydes, followed by an intramolecular enamination in the presence of 20 mol% of nanocry...
