A one-pot synthesis of 1,4-dithiins and 1,4-benzodithiins from ketones using the recyclable reagent 1,1′-(ethane-1,2-diyl)dipyridinium bistribromide (EDPBT)

A novel access to 1,4-dithiins and 1,4-benzodithiins from the corresponding ketones in one-pot using the recyclable reagent, 1,1′-(ethane-1,2-diyl)dipyridinium bistribromide (EDPBT) is described. This method is mild, simple, environmentally benign and is

Rapid method for the ring expansion of 1,3-dithiolanes and 1,3-dithianes with tert-rutyl hypochlorite

A new method for the ring expansion of 1,3-dithiolanes and 1,3-dithianes to dihydro-1,4-dithiins and dihydro-1,4-dithiepines, respectively, using lert-butyl hypochlorite at room temperature is described. The salient features of the protocol include mild r

New Applications of 2,4,6-Trichloro-1,3,5-triazine (TT) in Synthesis: Highly Efficient and Chemoselective Deprotection and Ring-Enlargement of Dithioacetals and Oxathioacetals

Efficient deprotection of a wide variety of 1,3-dithioacetals and 1,3-oxathiolanes to the corresponding carbonyl compounds at room temperature using a combination of 2,4,6-trichloro-1,3,5-triazine (TT) and dimethyl sulfoxide (DMSO) was investigated. In this way, 1,3-oxathioacetals and 1,3-dithioacetals of enolizable ketones were converted to the corresponding 1,4-oxathiepine and 1,4-dithiepine derivatives, respectively.

Reactions of silica chloride (SiO2Cl)/DMSO, a heterogeneous system for the facile regeneration of carbonyl compounds from thioacetals and ring-expansion annelation of cyclic thioacetals

Silica chloride (SiO2Cl)/DMSO, as a heterogeneous system, has been efficiently used for deprotection of thioacetals into aldehydes in dry CH2Cl2 at room temperature. Thioketals without enolizable hydrogens adjacent to a sulfur atom are converted easily to the corresponding ketones in high yields under similar reaction conditions. However, thioketals with enolizable methyl and methylene groups undergo ring-expansion reactions to afford 1,4-dithiepins and 1,4-dithiins in dry CH2Cl2 at room temperature in good yields.

Molybdenum pentachloride (MOCL5) promotes efficient ring-expansion and ring-expansion-chlorination of 1,3-Dithiolanes and 1,3-dithianes in the presence of DMSO. Part 3

Ring-expansion and ring-expansion-chlorination of 1,3-dithiolanes and dithianes conducted in the presence of MoCl5 and DMSO are described.

Tungsten hexachloride (WCl6) in the presence of dimethylsulfoxide promoted facile and efficient one-pot ring expansion-chlorination reactions of 1,3-dithiolanes and 1,3-dithianes

Tungsten hexachloride (WCl6) in the presence of DMSO could be efficiently used for the conversion of 1,3-dithiolanes and 1,3-dithianes to their corresponding chlorinated derivatives of dihydro-1,4-dithiin and dihydro-1,4-dithiepine in high yiel
