摘要:
The subject-matter of the invention is a process for preparing racemic or optically active epibatidine of formula which comprises cyclising a 1-[diacylamino]-2-[6'-chloro)-pyrid-3'-yl]-4-[amino]-cyclohexane of general formula wherein
Ac stands for an acyl group.
The advantage of the process is that readily available starting materials are used and the procedure is suitable for industrial scale productions, too.
摘要:
A subject-matter of the invention are oxaindene derivatives of general formula wherein
R 1 represents a C 1-4 -alkyl, C 1-4 -alkoxy or C 3-6 -cycloalkyl group, R 2 stands for hydrogen or a C 1-4 -alkyl or C 3-6 -cycloalkyl group, R 3 represents hydrogen or a C 1-4 -alkyl, C 1-4 -alkoxy or benzyloxy group, X means hydrogen, an aliphatic C 1-4 -acyl or benzoyl or naphthoyl group, optionally substituted by 1 or more nitro or C 1-4 -alkoxy group(s) or a group of formula in which latter R 7 stands for a C 1-4 -alkylene group and R 5 and R 6 each represents a C 1-4 -alkyl group or R 5 and R 6 together with the nitrogen atom to which they are attached form a piperidyl or morpholinyl group, A and B together form an ethylene or a vinylene group and n is 1, 2 or 3, and their stereoisomers and their mixtures as well as acid addition salts of these compounds. Moreover there are provided for a process for preparing these compounds, medicaments containing them and the use of these compounds. They have a strong 5-lipoxygenase enzyme inhibiting activity.
