SYNTHESIS OF Β-FUNCTIONALIZED α,β-DEHYDROAMINO ACID DERIVATIVES

β-functionalized α,β-unsaturated amino acids were synthesized by an addition-elimination pathway.Reaction of methyl β-bromo-α-formylaminoacrylates ( 3a-e ), which were prepared by the condensation of methyl isocyanoacetate ( 1 ) with aldehydes followed by

CHEMISTRY OF OXALYL DERIVATIVES OF METHYL KETONES. XLVI. REACTION OF β-BROMOAROYLPYRUVIC ESTERS WITH UREA

The substitution of the bromine atom in methyl β-bromoaroylpyruvates by urea is accompanied by cyclization of the substitution product.Depending on the reaction conditions, this leads either to 6-aroyl-5-hydroxyuracils or to 5-aryl-4-methoxycarbonyl-2,3-dihydro-2-imidazolones.

PHOTOCHEMICAL WOLFF REARRANGEMENT OF 5-DIAZO-6-PHENYLURACIL IN NEUTRAL SOLUTIONS. THE SYNTHESIS OF ALKYL 5-PHENYL-2-OXO-4-IMIDAZOLINE-4-CARBOXYLIC ACID DERIVATIVES

A photochemical Wolff rearrangement of 5-diazo-6-phenyluracil (6), the compound which does not form the corresponding hydrate or alcohol adducts, into alkyl 5-phenyl-2-oxo-4-imidazoline-4-carboxylic acid derivatives 8a-h in neutral solutions is described.
