A general, mild, and convenient method has been developed for the synthesis of various alkyl and aryl sulfinic acid salts and sulfonamides from the corresponding halides. Key to the success of this methodology is the design and facile synthesis of sodium 3-methoxy-3-oxopropane-1-sulfinate (SMOPS), a reagent that serves to introduce the protected sulfinate moiety directly to the substrate, thus avoiding
An efficientmethod is reported to synthesize sulfonamides on DNA from sulfinic acids or sodium sulfinates and amines in the presence of iodine under mild conditions. This method demonstrates a major expansion of scope of sulfonamide formation on DNA through the utilization of a novel sodium carbonate-sodium sulfinate bifunctional reagent class.
