Photolysis of N-hydroxy-2-thiopyridone esters derived from uronic acids of α-amino acids in presence of vinyl phosphonate affords the corresponding phosphonate derivatives. A convenient route for the synthesis of the isostere of AZT-5' monophosphate is de
MANIPULATION OF THE CARBOXYL GROUPS OF α-AMINO-ACIDS AND PEPTIDES USING RADICAL CHEMISTRY BASED ON ESTERS OF N-HYDROXY-2-THIOPYRIDONE

Photolysis of α-amino-acid or peptide esters derived from N-hydroxy-2-thiopyridone in the presence of t-butylthiol affords the expected decarboxylation products in good yield.The reaction can be applied to the α-carboxyl or to the side chain carboxyl of g
CONCISE SYNTHESES OF L-SELENOMETHIONINE AND OF L-SELENOCYSTINE USING RADICAL CHAIN REACTIONS

L-Selenomethionine and L-selenocystine were prepared in high overall yields from protected L-glutamic and L-aspartic acid derivatives respectively.Irradiation of the mixed anhydrides (esters) derived from 4 (e.g. 15) in the presence of dimethyldiselenide provided the protected L-selenomethionine 16 directly.We have shown that triselenocyanide Se3(CN)2 can serve as an efficient selenocyanating agent for radicals; the selenocyanide group is a good precursor for the diselenide moiety of L-selenocystine.
