Definitions
- the present invention relates to an intermediate for the synthesis of a protamine inhibitor, Aliskiren, and a process for the preparation of an intermediate. Background technique
- Aliskiren is an antihypertensive drug developed by Novartis with a novel pharmacological mechanism and is an orally effective non-peptide renin inhibitor acting on the renin angiotensin aldosterone system (RAS). Unlike existing drugs that act on angiotensin-converting enzyme inhibitors and angiotensin II receptor antagonists, aliskiren acts on the apocalyptic system of the renin-angiotensin system, which provides a blockade of the renin-angiotensin system. A new way.
- EP 678 503 discloses the construction of a chiral center linking isopropyl groups in a target molecule using an EVANS prosthetic group as a chiral source, and the specific synthetic route is as in Scheme 1.
- R is hydrogen or an amine protecting group such as benzyl, p-methoxybenzyl and the like.
- the invention also provides a method for preparing aliskiren, the method comprising the following steps:
- the intermediate I is subjected to a reduction reaction to obtain aliskiren, and the deprotection reaction of the amine group is carried out before or after the reduction, for example, when the R of the intermediate of the aliskiren represented by the formula (I) is an amine group. When protecting the group.
- the present invention also provides a process for the preparation of an intermediate of the formula (II), which comprises the following steps:
- the chiral iodide represented by the formula (V) is reacted with nitromethane to obtain an aliskiren intermediate represented by the formula ( ⁇ ).
- the reaction is carried out in dimethyl sulfoxide; preferably at 10 ⁇ Reaction at 30 ° C
- the present invention also provides a compound represented by the formula (VII) and a process for the preparation thereof, which comprises the steps of preparing a compound of the formula (VII) by amide coupling of a chiral acid represented by the formula (VI). .
- Intermediate
- the present invention also provides a process for the preparation of the intermediate III represented by the formula (III), which comprises the following steps:
- the aliskiren intermediate of the invention is easy to prepare and purify, and has the characteristics of low cost, safety and suitable for industrial production.
- the intermediate nitro aldol condensation reaction by further Aliskiren, reduced synthesis step, to improve the efficiency of the synthesis, has significant economic benefits c detailed description
