Simple dissolution of an arylalkyl acid chloride in 1,1,1,3,3,3-hexafluoro-2-propanol promotes an intramolecular Friedel-Crafts acylation without additional catalysts or reagents. This reaction is operationally trivial in both execution and product isolation (only requiring concentration followed by purification) and accommodates a broad range of substrates. Preliminary studies that bear upon potential reaction mechanisms are reported.

Example 164, (2010/01/31)
Compounds represented by formula (1),???whereinX is, for example, CH, CH2, CHR (wherein R is a lower alkyl group or a substituted lower alkyl group) or CRR' (wherein R and R' are the same as the above defined R);Y is, for example, CH, CH2or C=O;Z is, for exampe, O, S, S=O or SO2;U is C or N;R1to R4are each independently, for example, a hydrogen atom, OR, SR (wherein R is the same as defined above), or an aromatic ring, a substituted aromatic ring or a heterocycle;???at least one of R5and R8is, for example, OH and the remaining of R5and R8are each independently, for example, a hydrogen atom or OH, optical isomers thereof, conjugates thereof or pharmaceutically acceptable salts thereof are provided. These compounds are characterized in having a wide range of pharmacological actions such as an excellentrelaxing action of tracheal smooth muscles, an inhibition of airway hypersensitivity and an inhibition of infiltration of inflammatory cells into the airway and, in addition, high safety.

2-, 3- and 4-Methoxythiophenol, and 2,4-, 2,5- and 3,4-dimethoxythiophenol were transformed in two steps to the corresponding 2-(methoxyphenylthio)benzoyl chlorides XIII which were reacted with ammonia, methylamine, dimethylamine, diethylamine, dipropylamine, and di(2-propyl)amine to give the amides XIV-XIX.These were reduced mostly with lithium aluminium hydride to the amines II-VII.These methoxylated amines were demethylated mostly either by heating with pyridine hydrochloride or by treatment with boron tribromide.Some of the 2-(methoxy- and hydroxy-phenylthio)benzylamines prepared, especially compounds II, III, XXI, and XXII, indicated properties of potential antidepressants being highly active and selective inhibitors of 5-hydroxytryptamine re-uptake in the brain structures and having the typical antireserpine activity.The most interesting compound of the series is XXIb (hydrogen maleate VUFB-15 468) which is undergoing preclinical studies.On the basis of its structure, some further compounds (XXVII-XXIX, XXXIX-XLI) were prepared by various methods.
