| titleOfInvention | Process for producing polycyclic lactam |
| abstract | 1. A method of producing lactams of the following formula (1) comprising the following three steps A to C:n n[when R 3 and R 4 are both a hydrogen atom, R represents a substituted methylene group or an optionally substituted polymethylene group, when at least one of R 3 and R 4 is a substituent other than a hydrogen atom, R represents an optionally substituted methylene group or an optionally substituted polymethylene group, R 3 , R 4 , R 5 and R 6 represent each independently a hydrogen atom, halogen atom, cyano group, optionally substituted alkyl group, optionally substituted alkenyl group, optionally substituted aryl group, optionally substituted amino group, -OR a group, -SR b group or - COOR c group.] n(Step A) na step of reacting lactones of the following formula (2):n nand imides of any of the following formulae (3a), (3b) and (3c):n n[A 1 , A 2 , A 3 , A 4 , A 5 , A 6 , A 7 , A 8 , A 9 and A 10 represent each independently a hydrogen atom, halogen atom, nitro group, alkyl group, alkenyl group, optionally substituted aryl group, optionally substituted acyl group or -OR d .] to produce the correspondent carboxylic acids, n(Step B) na step of esterifying the carboxylic acids to produce the correspondent esters, n(Step C) na step of reacting the esters and amines to produce lactams of the formula (1). |
