  4. 2. Investigations of New Biomimetic Transamination Systems and Inclusion Complexation with Cyclodextrins

    Author : Anders Hjelmencrantz; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stereochemis; bicyclooctanes.Transamination; complexation; cyclodextrins; proton transfer; hydride transfer; stereochemistry; Transamination; Organic chemistry; Organisk kemi;

    Abstract : Two new transamination systems are described. The first example is a dibenzo[a,d]- cycloheptene containing system, designed to accomplish a [1,3]-hydride transfer. Several catalysts have been examined for this purpose. tris-Pentafluorophenyl borane was found to be the most efficient catalyst. READ MORE
