Appl. No.:

09/838989

Assignee:

Merck Co., Inc. - Rahway NJ

International Classification:

C07D33302

US Classification:

549 78, 568715

Abstract:

Processes are disclosed for preparing 3-hydroxymethylcyclopentanone compounds, which are useful as intermediates in the preparation of HIV chemokine CCR-5 receptor antagonists. A process is described in which the compounds are prepared by opening the cyclopropyl ring of a (1-alkoxycarbonyl-2-oxo)-trans-bicyclo[3. 1. 0]hexane compound by addition of a nucleophile to the cyclopropyl ring, and then decarboxylating the resulting 2-alkoxycarbonyl-3-(Nu-methyl)-cyclopentanone (Nu=the added nucleophilic group) via base solvolysis. Also described is a process for preparing the bicyclo[3. 1. 0]hexane precursors by the catalyzed cyclopropanation of a suitable alpha-diazo-beta-ketoester. The preparation of the alpha-diazo-beta-ketoesters and precursors thereto are also disclosed.

International Classification:

C07C317/24
A61K031/21

US Classification:

514509000, 558482000

Abstract:

The invention encompasses a novel process for making compounds of Formula I which are prodrugs of cyclooxygenase-2 selective inhibitors that convert in vivo to diaryl-2-(5H)-furanones and also liberate nitric oxide in vivo. As such, the compounds made by the present invention may be co-dosed with low-dose aspirin to treat chronic cyclooxygenase-2 mediated diseases or conditions, effectively reduce the risk of thrombotic cardiovascular events and potentially renal side effects and at the same time reduce the risk of GI ulceration or bleeding. The present invention describes an efficient and economical process for the preparation of 2,3-disubstituted (2Z)-4-acetoxybut-2-enoate derivatives that is useful for the production of kilogram quantities of material for preclinical and clinical use.
