Paragraph 0052, (2020/02/05)
PROBLEM TO BE SOLVED: To provide a BTBT ring (or DNTT ring)construction method in which a reaction proceeds under atmosphere and a low temperature (200°C or lower) without separately adding a substance to be a sulfur source as a raw material, and without using a raw material having corrosiveness, irritation, toxicity, and ignitability. SOLUTION: By using a specific thiol group-containing compound as a matrix raw material(starting compound), without adding a sulfur source substance, under atmosphere and low temperature (200°C or lower), a BTBT ring (or DNTT ring) may be obtained.

Phosphorus Pentasulfide Mediated Conversion of Primary Carbamates into Thiols

, p. 1649 - 1651 (2017/08/11)
In this paper, we report a method for the conversion of primary carbamates into thiols in the presence of phosphorus pentasulfide (P 2 S 5) in refluxing toluene. Presently, no method exists in the literature for conversion of carbamates into thiols and, to the best of our knowledge, it is the first report for this type of conversion. This method presents an indirect route for the conversion of alcohols into thiols via their carbamate derivatives that may be useful in the total synthesis of compounds containing a thiol functionality.

supporting information, p. 1184 - 1188 (2017/07/03)
In this paper we report an efficient and mild procedure for the conversion of organic thiocyanates to thiols in the presence of phosphorus pentasulfide (P2S5) in refluxing toluene. The method avoids the use of expensive and hazardous transition metals and harsh reducing agents, as required by reported methods, and provides an attractive alternative to the existing methods for the conversion of organic thiocyanates to thiols.

Novel imidazole mercaptals of the formula STR1 wherein each m is independently zero or one; and R1 and R2 each are independently selected from (lower)alkyl, cycloalkyl, cycloalkyl(lower)alkyl, phenyl, phenyl(lower)alkyl, thienyl, thienyl(lower)alkyl, pyridyl and pyridyl(lower)alkyl, in which the phenyl and heterocyclic rings optionally may contain from 1 to 3 substituents, and acid addition salts thereof, are useful antimicrobial agents.
Dioxalane containing imidazole compounds, compositions and use

, (2008/06/13)
Compounds useful as antifungal, antibacterial and antiprotozoal agents are represented by the formula: STR1 wherein: Z is oxygen or sulfur; R1 is phenyl optionally substituted with one or more substituents selected from the group consisting of halo, lower alkyl of one to four carbon atoms, lower alkoxy of one to four carbon atoms and trifluoromethyl; R2 is phenyl or benzyl wherein the phenyl ring of R2 is optionally substituted by one or more substituents selected from the group consisting of halo, lower alkyl of one to four carbon atoms, lower alkoxy of one to four carbon atoms and trifluoromethyl; or by a phenyl optionally substituted by halo, lower alkyl of one to four carbon atoms, lower alkoxy of one to four carbon atoms or trifluoromethyl; and the antimicrobial acid addition salts thereof.
