General Description

2,2-dimethyl-5-(2-thioxo-1,3-dioxolan-4-yl)tetrahydrofuro[2,3-d][1,3]dioxol-6-yl 4-methylbenzenesulfonate is a chemical compound with complex and specific structural characteristics. It is a sulfonate ester derivative of 4-methylbenzenesulfonic acid and contains a fused tetrahydrofuro[2,3-d][1,3]dioxol ring system with a thioxo-1,3-dioxolan-4-yl substituent at the 2 position and two methyl groups at the 2 position. The compound is also known as a non-preferred name, indicating that it may have alternative systematic naming conventions. This chemical may have applications in various industries, including pharmaceuticals, agrochemicals, and materials science, but its specific uses and properties would need to be further investigated.

Thio-sugars. I. Radical-promoted thione-thiol rearrangement of cyclic thionocarbonates: Synthesis of 5-thioglucose

The 5,6-O-thiocarbonyl-α-D-glucofuranose derivatives 2, when subjected to one of the following reactions, undergo a radical-promoted thione-thiol rearrangement to yield the 5-S-thiolcarbonates of gluco-configuration 8 as the major product. The reactions are, (A) thermolysis with a catalytic amount of tributyltin hydride and AIBN, (B) photolysis with hexabutyldistannane, and (C) thermolysis with dimethyl phosphonate and benzoyl peroxide. On the other hand, thermolysis of 2 with trialkylsilane (condition D) yielded olefins 13 as the major product. The 5-S-gluco product 8 was converted, in three steps, to 5-thioglucose (21) in 55% yield.
