| titleOfInvention | Process for producing new carbamoyl-oxy-alkyl-carboxy-lic acid derivatives |
| abstract | A process for preparing a 2-carbamoyloxyalkyl-1,4-dihydropyridine derivative represented by the general formula:n which comprises:n (a) reacting a 3-amino-3-carbamoyloxyalkylacrylic acid derivative represented by the general formula:n with a benzylidene compound represented by the general formula:n (b) reacting the 3-amino-3-carbamoyloxyalkylacrylic acid derivative of the general formula II with an aldehyde comoound reoresented bv the aeneral formula:n and a β-keto-ester compound represented by the general formula:n (c) reacting a 3-carbamoyloxyalkylpropiolic acid derivative represented by the general formula: with the benzylidene compound of the general formula III and ammonia or its salt: or (d) reacting the 3-carbamoyloxyalkylpropiolic acid derivative of the general formula VI with the aldehyde compound of the general formula IV, the β-keto-ester compound of the general formula V and ammonia or its salt, and the intermediates of formula II and VI. |
