Intermolecular Hydroalkoxylation of N-Allenyl Sulfonamides with Oximes Catalyzed by Cationic Gold(I) Salts
نویسندگان
چکیده
Intermolecular hydroalkoxylation of N-allenyl sulfonamides with oximes is achieved under mild gold(I)-catalyzed conditions delivering allyloximino E-enesulfonamides stereoselectively in moderate to high yields. The products contain two important functionalities, imines and enesulfonamides, within one framework containing an oxygen bridge, and the reaction is made possible via a convenient method for conjugated N-sulfonyliminium formation.

The utility of homogeneous gold complexes as carbophilic pacids has been well-established, with numerous reports of gold-catalyzed reactions that were initiated by addition of nucleophiles into unsaturated carbon–carbon bonds. Although protodeauration is common, several reactions have been developed in which the resulting organogold intermediate was intercepted. For example, nucleophilic reagen...
متن کاملStereoselective Gold(I)-Catalyzed Intermolecular Hydroalkoxlation of Alkynes
We report the use of cationic gold complexes [Au(NHC)(CH3CN)][BF4] and [{Au(NHC)}2(μ-OH)][BF4] (NHC = N-heterocyclic carbene) as highly active catalysts in the solvent-free hydroalkoxylation of internal alkynes using primary and secondary alcohols. Using this simple protocol, a broad range of (Z)-vinyl ethers were obtained in excellent yields and high stereoselectivities. The methodology allows...

A co-catalyst of (PPh3)AuCl/AgOTf for the intermolecular hydroamination of allenes with sulfonamides is shown. The reaction proceeded smoothly under mild conditions for differently substituted allenes giving N-allylic sulfonamides in good yields with high regioselectivity and E-selectivity.
متن کاملChirality Transfer in Gold(I)‐Catalysed Hydroalkoxylation of 1,3‐Disubstituted Allenes
Gold(I)-catalysed intermolecular hydroalkoxylation of enantioenriched 1,3-disubstituted allenes was previously reported to occur with poor chirality transfer due to rapid allene racemisation. The first intermolecular hydroalkoxylation of allenes with efficient chirality transfer is reported here, exploiting conditions that suppress allene racemisation. A full substrate scope study reveals that ...
