Process for producing novel naphthyridine derivatives

A novel naphthyridine derivative showing high activity as a tachykinin receptor antagonist can be produced at high efficiency by reacting an acylating agent such as a carboxylic acid derivative with a compound represented by the formula (1): wherein R1, R2 and R3 represent independently a hydrogen atom, a lower alkyl group, a lower alkoxyl group, an aryl group, a heteroaryl group, an amino group, etc., and X1 and X2 represent respectively a halogen atom.

Synthesis and Reactions of Perfluorobutanesulfonyl Hypohalites

Two new hypohalites, perfluoro-n-butanesulfonyl hypochlorite and hypobromite, are reported.The hypochlorite is prepared by the low-temperature reaction of ClF with the acid C4F9SO2OH.The hypobromite is prepared by reaction of the hypochlorite with bromine.The new compounds contain very electrophilic halogen atoms and exhibit reactions similar to the analogous trifluoromethanesulfonates, CF3SO2OX (X=Cl, Br).The new hypohalites exhibit somewhat greater stability than the trifluoromethanesulfonates but form analogous decomposition products.Characterization of the newcompounds is given along with several reactions with olefins and halides to yield a variety of new esters.
