Asymmetric synthesis of polyhydroxy alpha-amino acids with the sulfinimine-mediated asymmetric strecker reaction: 2-amino 2-deoxy L-xylono-1,5-lactone (polyoxamic acid lactone)



Asymmetric synthesis of polyhydroxy alpha-amino acids with the sulfinimine-mediated asymmetric strecker reaction: 2-amino 2-deoxy L-xylono-1,5-lactone (polyoxamic acid lactone)



Journal of Organic Chemistry 67(22): 7802-7806



Polyhydroxylated sulfinimines derived from protected 1,2-O-isopropyliden-L-threoses undergo the sulfinimine-mediated Strecker syntheses to give alpha-amino nitriles in good yield and de. A double stereodifferentiation effect was not observed and the diastereoselectivity is controlled by the absolute configuration of the sulfinyl group.
