AbstractAn asymmetric organocatalytic nucleophilic aromatic substitution reaction of azlactones with electron-deficient aryls was established. A variety of α-aryl α-alkyl α-amino acid esters and peptides were obtained in decent yields and stereoselectivities. A new bifunctional catalytic mode involving charge-transfer interaction and hydrogen bonding is proposed to explain the enantioselectivity.

The photolysis of N-aryl-carbamic acid alkyl esters in methanol was investigated. The primary products, amino-benzoic acid esters and aromatic amines, result from photo-Fries rearrangements and splitting processes.2,4,6-Trimethylphenyl-carbamic acid ethyl ester and N-alkyl-carbamic acid alkyl esters form photolysis products only through homolytic splitting reactions.The photooxidation of N-substituted urethanes has been investigated in tert.-butanol. The main products are primary amines and CO2.These initially formed compounds are then further oxidized. In the aliphatic substituted derivatives, oxidation of the N-alkyl group results followed homolytic bond splitting.
