Abstract
Procedure for obtaining carboxylic derivatives, of the general formula: **(See formula)** in which R1 represents a group: **(See formula)** R2 represents a group that has the general formula: **(See formula)** in which R3, R4 and R5 each represent a hydrogen atom or a methyl or ethyl group, and R6 represents a group: -CH3; -CH2-CH3 - (CH2) 2-CH3; -CH (CH3) 2; - (CH2) 3-CH3; -C (CH3) 3; -CH (CH2-CH3) 2 or **(See formula)** whose procedure comprises reacting a compound of the general formula: **(See formula)** in which formulas R1 has the meaning indicated above, R7 represents a methylene group and R8 represents an alkali or tertiary ammonium cation, with a compound of the general formula: **(See formula)** where R3, R4, R5 and R6 have the meanings indicated above, X represents a removable radical, such as a chlorine, bromine, or iodine atom, or an acyloxy or arylsulfonyl group, to obtain respectively a compound of the general formula: **(See formula)** in which formulas R1, R2 and R7 have the meanings indicated above, subjecting these compounds to selective acid hydrolysis, in order to produce the desired compounds, of formulas I, II or III, respectively.
