Oxathiane dioxides synthesis

Oxathiane dioxides lithiated 641 synthesis of 638, 647 Oxathiane oxides, synthesis of 352 Oxathiolane oxides, synthesis of 241 Oxaziridines 72, 254, 826 as optically active oxidizing agents 291 Oxazolidinones 826 Oxazolines 619, 788... 

This procedure represents the first reported synthesis of cis- and further reaction product, 4//-l,4-thiazine 1,1-dioxide. A derivative of the latter, 3,5-diphenyl-4//-l, 4-thiazine 1,1-dioxide,... 

Further, a 1,2-oxathiane 2,2-dioxide derivative was obtained as a by-product (15-25%) in the enantioselective synthesis of Oasomycin A <2007AG545> all efforts to suppress this side reaction were not successful, and the reaction products of the hexafluorobutadiene sulfotrioxidation (among the main products a 4,5-dihydro-l,2-oxathiin 2,2-dioxide derivative) were identified by F NMR spectroscopy <2007RJA424>.
