(Chemical Equation Presented) Light from a mercury vapor high-pressure lamp was used to induce the photolytic decomposition of α-diazo acetamides in hexane and in nonconventional media such as water or a film. The corresponding a- and/or γ-lactams were ob
Stereoselective alkylation of C2-symmetric chiral N- phthaloylglycinamides in the preparation of enantiopure α-amino acids

The novel, chiral glycinamides (S,S)-3 and (S,S)-4 were prepared in good yields from C2-symmetric chiral amines (S,S)-1 and (S,S)-2, respectively. Enolate formation and addition to methyl iodide and benzyl bromide proceeded in good yield and high diastereoselectivity, especially in the presence of LiCl or DMPU. Removal of the phthaloyl protecting group with hydrazine, followed by hydrolysis with 6N HCl, converted the benzylated product (S,S,S)- 7 to enantiopure (S)-phenylalanine.
