AN IMPROVED PROCESS FOR THE PREPARATION OF FROVATRIPTAN

A process for the preparation and purification of Frovatriptan of formula (I) and its enantiomers, particuariy the R- enantiomer is disclosed, comprising formation of the di-p-toluoyltartaric acid salt of Frovatriptan.

METHOD FOR PRODUCING CARBONYL COMPOUND AN PRO-OXIDANT USED FOR PRODUCTION OF CARBONYL COMPOUND

The invention provides a process for the preparation of a carbonyl compound in high efficiency by oxidizing an alcohol. The process for the preparation of a carbonyl compound of the present invention includes a step of oxidizing an alcohol in the presence of a compound of the formula (I) or a derivative or a salt thereof, and an oxidant, wherein R1 and R2 independently represent hydrogen, a halogen, a nitro or acidic group, or an alkyl or alkoxy group, each of which optionally has a substituent, or R1 and R2 combine the two carbon atoms to which they are boned to form an aromatic ring.

A new efficient deprotection of azines, hydrazones and oximes. An excellent route for exchanging oxygen isotopes in carbonyls

Carbonyls, protected as azines or other C=N derivatives can be deprotected by HOF·CH3CN in seconds to the corresponding ketone or aldehyde in very good yields. This reaction also offers a very efficient route for replacing the oxygen atom of most carbonyls with any other oxygen isotope, for example, [18]O.
