Synthesis of BOC-CYS-ALA-OME and its stereoselective addition to α-methylene-γ-butyrolactones

Add time:08/04/2019    Source:sciencedirect.com

The stereoselective addition of enantiomerically pure (as shown by 200 MHz 1H NMR study) dipeptide Boc-Cys-Ala-OMe 4 to α-methylene-γ-butyrolactones has been studied. The stereoselectivity of the addition parallels the enantioselectivity observed in the allergic contact dermatitis induced in guinea pigs.
