摘要:1. New thiophene compounds of the formula: in which: X represents hydrogen, halogen, C1-C5alkyl or alkoxy or dialkylamino; n represents 1 or 2; a represents an integer of from 2 to 6; b represents 2 or 3; c represents 1 or 2, and is such that b+c=4; R1 and R2 represent hydrogen or (C1-C5)alkyl, or together with the carbon atom to which they are bonded form a hydrocarbon ring containing from 3 to 6 carbon atoms; and R and R' represent hydrogen or (C1-C5)alkyl, or together with the nitrogen atom to which they are bonded form a pentagonal or hexagonal heterocycle optionally containing an oxygen atom or a second nitrogen atom which may itself be substituted; and their physiologically tolerable salts. The products of the invention can be used therapeutically especially in the treatment of pathologies that are characterized by a loss of bone tissue. 2. As new intermediate products used in the synthesis of the compounds I above defined, the amides of the formula: in which: X, n, a, b, c, R1, R2, R and R' are as above defined.
