The novel title cpds. are of formula:- (in which Q is CHO, CH2OH, COOR' or CH2OCOR", where R' is H or 1-4C alkyl and R" is 1-4C alkyl; R1 is n-butyl, n-pentyl, or n-hexyl; R2 is H, 1-3C alkyl, 3-6C cycloalkyl or -COR", the two R2 gps. being identical; and X is CO or CHOH, with the provisos that when Q is CHO, X is CO; when R2 is COR", Q is CH2OCOR", when R2 is H, Q is not CH2OCOR", and when there is >=1 R" gp. in the molecule, these are identical), and claims include the salts of cpds. in which Q is COOH. |
