Phosphoric Acids

A new highly enantioselective route to α-alkenyl α-amino acid derivatives using a N–H insertion reaction of vinyldiazoacetates and tert-butyl carbamate cooperatively catalyzed by achiral dirhodium(ii) carboxylates and chiral spiro phosphoric acids was developed.

N-Methyl β-amino acids are potentially useful amino acid derivatives for incorporation in lead peptide therapeutics. The syntheses of five such compounds are presented. Their synthesis via 6-oxazinanones was low yielding. Alternatively, reductive cleavage of a 5-oxazolidinone gave the N-methyl α-amino acid, which was then homologated via an Arndt–Eistert procedure in high yield to give the N-methyl β-amino acid.
