Title: Method of preparing d-amino acid-n-(s)-.alpha.-alkylbenzylamide
Inventor: HIJIYA TOYOTO
IPC: C07B53/00
Filed: 1995-11-28
Abstract: L-amino acid amides are converted to the corresponding D-amino acid amides. An amide formed from an L-amino acid and an optically active (S)-.alpha.-alkylbenzylamine is subjected to dehydration conden-sation with an  aryl  aldehyde  to  form a  Schiff's base, which is racemized at the amino acid moiety in the presence of  a base promoting  racemization to yield  an  N-allylidene-D-amino  acid-(S)-amide.  The less-soluble diastereomer N-allylidene-D-amino acid-(S)-amide is crystallized from the reaction mixture and recovered by means of solid/liquid separation. The N-allylidene form is readily hydrolyzed into the D-amino  acid-(S)-amide  and the  starting  aldehyde. The method of the invention enables one to prepare D-amino   acid-M-(S)-.alpha.-alkylbenzylamides   of the formula:                           (I) wherein the carbon atom indicated by an asterisk (*) has a D-amino acid structure, R1 is an alkyl group having from 1 to 4 carbon atoms and R2 is a methyl or ethyl group, which can be used as intermediates for  the  preparation  of  substances  having intense sweetness.
