Mali, Sachitanand M. published the artcileSynthesis of α, β-unsaturated γ-amino esters with unprecedented high (E)-stereoselectivity and their conformational analysis in peptides, Recommanded Product: (R)-tert-Butyl (3-methyl-1-oxobutan-2-yl)carbamate, the publication is Organic & Biomolecular Chemistry (2011), 9(19), 6566-6574, database is CAplus and MEDLINE.
Mild, efficient and racemization-free synthesis of N-protected α, β-unsaturated γ-amino esters with unprecedented high E- stereoselectivity is described. This method is found to be compatible with Boc- (Boc = tert-butoxycarbonyl), Fmoc- (Fmoc = 9-fluorenylmethoxycarbonyl) and other side chain protecting groups. The crystal conformations of the vinylogous γ-amino esters in monomers and in homo- and mixed dipeptides are studied. Further, the vinylogous homo-dipeptide showed a β-sheet conformation, while mixed α- and α,β-unsaturated γ-hybrid dipeptide adapted an irregular structure in single crystals.
