REACTIONS OF N-HYDROXYSUCCINIMIDE ESTERS OF N-ALKOXYCARBONYL-ALPHA-AMINO ACIDS WITH ACTIVE METHYLENE-COMPOUNDS - SYNTHESIS OF 3-SUBSTITUTEDTETRAMIC ACIDS
A. Detsi et al., REACTIONS OF N-HYDROXYSUCCINIMIDE ESTERS OF N-ALKOXYCARBONYL-ALPHA-AMINO ACIDS WITH ACTIVE METHYLENE-COMPOUNDS - SYNTHESIS OF 3-SUBSTITUTEDTETRAMIC ACIDS, Chemical communications, (11), 1996, pp. 1323-1324
The N-hydroxysuccinimide esters of N-alkoxycarbonyl-alpha-amino acids
react with active methylene compounds (cyanoacetic esters,malonic and
acyl acetic esters), under basic conditions, to produce 3-substituted
N-alkoxycarbonyl tetramic acids; in the case of the N-hydroxysuccinimi
de esters derived from L-aminoacids, the corresponding optically activ
e tetramic acids are obtained.
