The Highly Stereocontrolled Radical-based Addition of a 2,2-Dichloroacyl Function to a 2-Oxazolone Heterocycle. A New Approach to MeBmt, the Key Component of Cyclosporin
The Highly Stereocontrolled Radical-based Addition of a 2,2-Dichloroacyl Function to a 2-Oxazolone Heterocycle. A New Approach to MeBmt, the Key Component of Cyclosporin
Stereoselective intramolecular radical addition of polyhaloacyl pendant groups to the 1,3-dihydro-2-imidazolone moiety: the chiral synthesis of threo-diaminocarboxylic acids
addition of trichloroacetyl and 2,2-dichloro-4-hexenoyl pendant groups to a 1,3-dihydro-2-imidazolone moiety provides a perfectly stereocontrolled approach to the preparation of 1,2-diamines which contain contiguous multi-stereocenters. Typical examples for this approach are given by the chiral synthesis of vicinal-diaminocarboxylic acids, which are amino analogs of statine and MeBmt.
