Base-catalyzed Povarov reaction: an unusual [1,3] sigmatropic rearrangement to dihydropyrimidobenzimidazoles.
A novel base-catalyzed Povarov reaction of arylamines, aldehydes, and electron-deficient dienophiles has been developed. An unprecedented in situ [1,3] sigmatropic rearrangement leading to 4,10-dihydropyrimido[1,2-a]benzimidazoles has also been discovered. An insight of the plausible mechanism is discussed and supported by X-ray crystal study. This cascade reaction is achieved in a one-pot mult...
متن کاملCatalytic asymmetric [2,3]-sigmatropic rearrangement of sulfur ylides generated from copper(I) carbenoids and allyl sulfides.
Catalytic asymmetric sulfur ylide [2,3]-sigmatropic rearrangement of carbenoids generated from aryldiazoacetates has been investigated with a number of chiral Rh(II) and Cu(I) catalysts, and moderately high enantioselectivity (52-78% ee) can be achieved with Cu(MeCN)(4)PF(6)/2,2'-isopropylidenebis[(4S)-4-tert-butyl-2-oxazoline].

Catalytic asymmetric [2,3] sigmatropic rearrangement of sulfur ylides generated from aryldiazoacetates and propargyl sulfides with a number of chiral Rh(II) and Cu(I) catalysts have been investigated and moderately high enantioselectivities (up to 81% ee) have been achieved. © 2003 Elsevier Science Ltd.

متن کاملHighly stereoselective [2,3]-sigmatropic rearrangement of sulfur ylide generated through Cu(I) carbene and sulfides.
A highly stereoselective [2,3]-sigmatropic rearrangement of sulfur ylide generated through Cu(I) carbene and allyl and propargyl sulfides by a double asymmetric induction approach that combines a chiral camphor sultam auxiliary and Cu(I) catalyst with chiral or achiral diimine ligands has been developed.
متن کاملBase-Catalyzed Rearrangement of Some 1,3-Oxathiolane Sulfoxides: Mechanistic Viewpoint of the Sigmatropic and Elimination Reactions
Rearrangements of 1,3-oxathiolane sulfoxides 8 and 9 in the presence of base are described from a mechanistic viewpoint of sigmatropic and elimination reactions. In the presence of triethylamine the (Z)sulfoxide 8 gave the corresponding thiolsulfinate 10 by way of dimerization of the sulfenic acid intermediate 2 at room temperature while the (E)-sulfoxide 9 was recovered even after refluxing in...
