摘要:
A convenient method for converting oximes into enamides is disclosed. The process produces enamides without the concomitant production of a large volume of metallic waste. The enamides are useful precursors to amides and amines.
摘要:
The invention relates to novel derivatives of short-chain fatty acids, in particular derivatives of butyric acid, useful for all the known clinical applications of the latter, which show physicochemical characteristics suitable for an easy oral administration, being devoid of the unpleasant organoleptic properties that characterize butyrate. The new compounds are amide derivatives which can be synthesized by reaction of the corresponding fatty acid halide with a naturally occurring amino acid, phenylalanine or a suitable derivative thereof, and which are in a poorly hygroscopic, easily weighable form, stable to acids and alkalis and able to release the acid at the small and large bowel level in a constant manner over time. They do not have disagreeable odors and are practically tasteless, thus allowing the manufacture of preparations for oral administration also suitable for the therapy of chronic diseases and in the pediatric field.
摘要:
Disclosed are a process suited to large scale synthesis with high yield for producing oseltamivir phosphate, in which a preparation of oseltamivir phosphate which is highly safe as a pharmaceutical product can be produced, and an intermediate compound for producing oseltamivir phosphate. In this production process, an intermediate compound represented by general formula (V) is synthesized by employing Michael reaction/Michael reaction/Horner-Wadsworth-Emmons reaction, and oseltamivir phosphate is produced by converting the substituent groups in this intermediate compound.

Alternatively, R.sub.1 and R.sub.2 may jointly form a substituted or unsubstituted, saturated or unsaturated heterocycle having from four to eight carbon atoms, N being a hetero atom of the resulting heterocycle. R.sub.3 may be either hydrogen or C.sub.1-3. In the compounds, a total sum of carbon atoms comprising R.sub.1 or R.sub.2, (CH.sub.2).sub.n and (CH.sub.2).sub.m does not exceed forty. R.sub.4 is a terminal moiety comprising a substituted or unsubstituted, oxidized or reduced ring system, the ring system having a single ring or two to three fused rings, a ring comprising from three to seven ring atoms. The disclosed compounds are effective agents to inhibit undesirable responses to cell stimuli.
