N-monosubstituted β-aminoacrylates are building blocks, which have been used in the preparation of amino acids and pharmaceuticals. Two efficient, stereoselective methods of preparation, via acid- or base-promoted condensation reactions of carbamates, are described. The base-promoted reaction is E-selective, while acid catalysis can, through the choice of solvent, selectively form E or Z. The acid-catalyzed E-selective process proceeds through a crystallization obviating the need for chromatographic purification.

FSM-16, a mesoporous silica, was found to catalyze oxidative photo-decarboxylation of α-hydroxy carboxylic acid, phenyl acetic acid derivatives and N-acyl-protected α-amino acids to afford the corresponding carbonyl compounds. Furthermore, FSM-16 proved to be re-usable by re-calcination at 450°C after the reaction.

FSM-16, a mesoporous silica, was found to promote the oxidative photodearboxylation of N-acyl-protected α-amino acids in hexane to afford the corresponding imides.
Irreversible Inhibition of Mammalian and Insect Peptidylglycine &α-Hydroxylating Monooxygenases (PHMs), Peptide Amidating Enzymes, by N-Formyl Amides
Klinge, Michael,Cheng, Hengmiao,Zabriskie, T. Mark,Vederas, John C.
, p. 1379 - 1380 (2007/10/02)
A series of N-formyl amides were synthesized by condensation of N,N-bis(trimethylsilyl)formamide with acid chlorides (59-90percent yields), or by reaction of hydroxyglycyl peptides with 90percent hydrogen peroxide (45percent yield); a number of N-formyl amides which bear a phenyl substituent are mechanism-based irreversible inactivators of peptidylglycine α-hydroxylating monooxygenases purified from pig pituitary and from honeybee heads.
