DOI: 10.1021/acs.orglett.4c00432
Abstract: A metal-free photosensitized 1,2-imino-sulfamoylation of olefins by employing a tailor-made sulfamoyl carbamate as the difunctionalization reagent has been established. This protocol exhibits versatility across a broad substrate scope, including aryl and aliphatic alkenes, leading to… read more here.

DOI: 10.1021/acs.orglett.4c03170
Abstract: We report Cu-catalyzed enantioselective borylation/oxidation sequences that afford either enantioenriched 1,2- or 1,3-amino alcohols starting from N,N-protected allylamines as a common platform. The approach is based on the mechanistic specificities of catalytic hydroboration and protoboration… read more here.

DOI: 10.3762/bjoc.15.65
Abstract: A highly efficient and convenient protocol was developed to access 2-amino-4H-benzothiopyran-4-ones through a process of conjugated addition–elimination. The sulfinyl group was proved to be the optimum leaving group by thorough investigations on the elimination of… read more here.
