&(1-Uracilyl)-a-substituted propionitriles were obtained by cyanohydrin synthesis from 1-uracilylacetaldehydes. Their hydrolysis, bromination, and amination were studied.

We have previously shown that, depending on the reaction conditions, either replacement of the bromine atom by an amino group or cine substitution with the formation of t0-(6-alkylamino-l-uracilyl)alkylamines or intrarnolecular cyclization, which leads to imidazo[1,2-c]-or pyrimido[1,2-c]pyrimidine systems occurs in the reaction of B-(5-bromo-l-uracilyl)-aaminopropionic acid and to-(5-bromo-l-uracilyl)ethyl(propyl)amines with primary and secondary amines [1][2][3]. Intramolecular C(6)--O(5 D cyclization is observed when 2',3'-isopropylidene-5-bromouridine is heated with sodium ethoxide in ethanol, and the corresponding 6,5'-cyclonucleoside is formed in high yield [4].

We felt it was expedient to investigate the behavior of B-(5-bromo-l-uracilyl)-a-hydroxypropionic acid under similar conditions.

b-Substituted a,b-dehydroamino acids are synthesised in high yields by a Michael addition of heterocyclic nucleophiles to the methyl esters of N-tert-butyloxycarbonyl,N-(4-toluenesulfonyl)dehydroamino acids, followed by a base-induced elimination of the 4-toluenesulfonyl group with regeneration of t
