| titleOfInvention | PROCEDURE FOR THE PREPARATION OF DERIVATIVES OF BETA-AMINO-ACRYLIC ACID. |
| abstract | Procedure for the preparation of derivatives of beta-amino acrylic acid of formula I **(See formula)** (where R represents an optionally substituted alcoholic, aryl, or aralkoxy group or a group of the formula - (CH2) n-COOR4 where n is 1, 2, or 3 and R4 is hydrogen, alcoholic, or aralkoxy; R1 and R2 are hydrogen or together form a group of the formula -CH = CH-CH = CH- attached at the 2,3 or 3,4-positions; ring A may optionally carry one or more substituents; X and Y represent -CH = or - N =, where -CH = at least one of the symbols X and Y; and R3 is hydrogen, alcoholic or aralcohyl), and tautomeric forms and salts thereof, which comprises reacting a compound of formula II **(See formula)** (in which R1, R2, X, Y and A have the same meanings as indicated above) with a 2-formyl-acetic acid derivative of formula III **(See formula)** (where R and R3 have the same meanings as indicated above); if desired, esterify an acid of formula I thus obtained in which R3 is hydrogen; if desired, converting an ester of formula I, in which R3 is alcoholic or aralcohyl, into the corresponding acid; and, if desired, converting a compound of formula I thus obtained into one of its salts.
