An unprecedented asymmetric acyl-carbamoylation of pendant alkenes tethered on aryl carbamic chlorides with both aliphatic and aromatic aldehydes has been developed via the cooperative catalysis of a chiral nickel-PHOX complex and tetrabutylammonium decatungstate. This reaction represents the first example of merging hydrogen-atom-transfer photochemistry and asymmetric transition metal catalysis in difunctionalization of alkenes. Using this protocol, a variety of oxindoles bearing a challenging quaternary stereogenic center are furnished under mild conditions in highly enantioselective manner.

N-Allyl-2-methyl aniline [1a], N-allyl and N-(2'-methyl-allyl)-N-methyl anilines[1b and 1c, respectively] undergo the 3-aza-Cope rearrangement in presence of HY-Zeolite, HEMT and HZeolite beta in hexane at 80°C to give Indoline derivatives as the major pr
