secondary alkylamines with activemethylenecompounds afforded mono-sulfenylated compounds in good yields. The reactions of 2 mol of sulfenamides derived from imides with 1 mol of activemethylenecompounds in the presence of a base gave di-sulfenylated compounds. It was found that α-mono-sulfenylated ketones were prepared by the reactions of enamines with sulfenamides derived from imides. α-gem-Di-sulfenylated
Phenylsulphenamides react chemoselectively with an alkene and a nitrile in the presence of trifluoromethanesulphonic acid to give -(β-phenylthioalkyl) amidines; in the absence of nitrile an amine is formed.

AbstractSulfenamide and its derivatives (S–N bond) have been synthesized with classical method in the literature. However, microwave-assistedsynthesis of a series of N-(substituted phenylthio), N-(benzylthio), N-(cyclothio), and N-(2-mercaptobenzimidazolyl)amines has been not in the literature yet. They have been obtained from treating some amines (4 mmol) with thiophthalimides (PhthSR, 1 mmol) using

[Problems]
To provide a pyrrolidine analogue having an inhibitory activity on the induction of allodynia, a method for producing the pyrrolidine analogue, and an agent for preventing a neurogenic pain.
[Means for Solving the Problems]
A pyrrolidine analogue which is a compound represented by the general formula (I) [wherein HOOC-ϕ represents an aromatic substituent having at least one carboxy group attached to the benzene ring] or a salt or ester of the compound. The compound has a potent inhibitory effect on the induction of allodynia.
