Oxidation Synthesis

A one-pot catalytic method has been developed for the stereoselective synthesis of cyclopropane-fused cyclic amidines using CuBr2/K2S2O8 as an efficient single electron transfer (SET) oxidative system. The generality of this...

Sulfonate Ester

The one-pot conversion of a mercaptan and an aryl methanesulfonate into a trithioorthoformate is described. The intermediacy of a sulfide-sulfonate ester is firmly established. Experimental and computational results permit the formulation of a possible pathway for the formation of the intermediate sulfide-sulfonate ester. Keywords: single electron transfer, sulfonate esters, sulfide-sulfonate esters.

Sulfonate Ester

A previous report has established the intermediacy of a sulfide-sulfonate ester in the one-pot conversion of an aryl mercaptan and a sulfonate ester into the corresponding trithioorthoformate. This report describes evidence for the sequential intermediacy of a bissulfide-sulfonate ester and a dithiosulfène in the conversion of the sulfide-sulfonate ester into the trithioorthoformate. A new sulfonate ester is shown to give the highest yield of trithioorthoformate. Key words: single electron transfer, sulfonate esters, sulfenes.

Isatin Derivatives

The utilities of ytterbium(II) reagent, both as nucleophilic reagent and single electron transfer reagent in the reaction of isatin derivatives with ytterbium(II) reagent are reported for the first time in this paper. From a synthetic point of view, a general, efficient, and experimentally simple one-pot method for preparation of 3-substituted-2-oxindoles was developed.
