A method is disclosed for preparing a synthetic intermediate for treprostinil via a stereoselective alkyne addition reaction using a chiral inducing agent. Also described are methods of preparing treprostinil or a pharmaceutically acceptable salt thereof comprising the alkyne addition reaction as well as novel intermediates useful for synthesis prostacyclin derivatives. A functional alcohol protecting group protects the alcohol group from participating in reactions that are occurring in other parts of the molecule. The intermediate is later deprotected prior to conversion and hydrolyzing to obtain the final treprostinil product.
The present invention relates to a condensed heterocyclic compound that has an enteropeptidase inhibitory effect and is useful in the treatment or prevention of obesity, diabetes mellitus, or the like, and a medicament containing the same. Specifically, the present invention relates to a compound represented by the following formula (I) or a salt thereof, and a medicament containing the same [in the formula, each symbol is as defined in the specification].
