PROCEDURE FOR THE PREPARATION OF ACIDS (2-OXO-3-TETRAHIDROTIENILCARBAMOIL) -ALQUILTIO ACETICOS. |
| abstract |
PROCEDURE FOR THE PREPARATION OF (2-OXO-3-TETRAHIDROTIENILCARBAMOIL) -ALKYLTIO) ACETIC ACIDS. A 3-HALOACIL AMINO-2-OXO-TETRAHYDROTHIOPHENE OF FORMULA (II) IS REACTED WITH A THIOGLYCOLIC ACID HS-CH-COOR, IN THE PRESENCE OF A PROTON ACCEPTOR AT A TEMPERATURE OF 15 TO 120 C. WHEN R IS HYDROGEN THE PRODUCT OBTAINED (I) IS TRANSFORMED INTO ITS ALKALINE SALTS AND THEIR CORRESPONDING ESTERS; N IS 0 OR 1 WHILE ONE OF THE SUBSTITUENTS R AND R ARE A HYDROGEN ATOM OR A METHYL GROUP AND THE OTHER IS A -S-CH -COOR GROUP. |
