Preparation method of beta-carboxyl phosphate

The invention provides a preparation method of beta-carboxyl phosphate. The preparation method comprises the following steps: carrying out regional selective ring-opening reaction on an epoxy compound and trialkyl phosphite to generate beta-carboxyl phosphate intermediate; and then oxidizing the beta-carboxyl phosphate intermediate to obtain the beta-carboxyl phosphate. The method is gentle in reaction condition and simple and convenient to operate without protection of an anhydrous solvent and oxygen, and is suitable for large-scale production. The beta-carboxyl phosphate synthesized by the preparation method can be used as an important intermediate synthesized by various misoprostols, such as travoprost, bimatoprost and tafluprost.

Synthesis of (±) travoprost and its analogs

A new synthetic approach for the antiglaucoma agent, travoprost (1) has been developed in four steps from key intermediate (2). Key transformations include Horner-Wadsworth-Emmons reaction and separation of diastereomers to obtain (±) travoprost (1) and its analogs.

N-(Methanesulfonyl)-16-phenoxyprostaglandincarboxamides: Tissue-Selective, Uterine Stimulants

In an effort to develop tissue-selective prostaglandin analogues resistant to the metabolic inactivating pathways of the natural materials, hybrid compounds modified both at C-1 with a sulfonimide moiety and in the n-amylcarbinol side chain with substituted phenoxy groups were synthesized and evaluated in a variety of in vitro and in vivo models.Several of these analogues exhibited potent, tissue-selective, uterine stimulant activity, a finding subsequently confirmed in clinical studies with one member of this series, N-(methanesulfonyl)-16-phenoxy-ω-tetranor-PGE2-carboxamide (CP-34089/ZK-57671, sulprostone).
