3-Dimethoxypropylsulfonyl (Dimps) chloride was prepared and used as a new versatile sulfonating agent for ammonia, primary and secondary amines to afford corresponding Dimps-amides in excellent yields. The resulting N-nonsubstituted and N-monosubstituted Dimps-amides, activated amines, were alkylated satisfactorily under new Mitsunobu conditions. The Dimps group was removed by treatment in aqueous solution under acidic

Treatment of selected terpenylalkanolamines containing isopropylidene moieties with an excess of sodium nitrite in aqueous acetic acid affords the corresponding ethylidyne N-nitrosamines.
Hepatic diseases can be prevented or treated by administering an isoprenylamine derivative represented by the general formula (II)
[wherein n represents an integer of 4 - 12, m represents an integer of 0 - 3, Ar represents a phenyl group, a furyl group, a thienyl group or a pyridyl group, said group being optionally substituted with one or more of an alkyl group of 1 - 4 carbon atoms, and alkoxy group of 1 - 4 carbon atoms, a methylenedioxy group, a hydroxy group or a halogen atom, and R represents a hydrogen atom or an alkyl group of 1 - 4 carbon atoms] or a pharmacologically acceptable salt thereof at a daily dose of 0.01 - 500 µg/kg.
A lipid emulsion of the compound (II) is particularly useful and can be administered at a remarkably lowered dose as compared with other pharmaceutical preparations.
