Synergistic chiral iminium and palladium catalysis: Highly regio- and enantioselective [3 + 2] annulation reaction of 2-vinylcyclopropanes with enals
A cooperative catalytic strategy of chiral iminium catalysis by regioselective activation of the C=C bond in enals and a transition metal promoting to open the 2-vinylcyclopropanes for highly regio- and enantioselective [3 + 2] cycloaddition reaction of 2-vinylcyclopropanes with α,β-unsaturated aldehydes has been developed.
متن کاملarylaminotetrazoles : via [2+3] cycloaddition of nitriles and sodium azide via solid acid catalysis
The [3+2] cycloaddition between various nitriles and sodium azide proceeds smoothly in the presence of zeolite and sulfated Zircona as effective catalyst and in the water and DMF/MeOH, to give the corresponding arylaminotetrazoles in good to high yields. The reaction most probably precedes through the in situ formation of a catalyst azide species, followed by a successive [3+2] cycloaddition wi...
متن کاملReaction of alpha-ene-vinylcyclopropanes: type II intramolecular [5+2] cycloaddition or [3+2] cycloaddition?
Exposure of alpha-ene-VCPs to catalytic [Rh(dppm)]SbF(6) led to the discovery of a novel Rh(I)-catalyzed [3+2] reaction, which was shown to be efficient for the construction of 5/6- and 5/7-bicyclic compounds rather than the anticipated type II [5+2] products.
