Aminoxidation of Arenethiols to N-Chloro-N-sulfonyl Sulfinamides

A simple and efficient method to synthesize N-chloro-N-sulfonylsulfinamides by the direct aminoxidation of arenethiols under aqueous and mild conditions is disclosed, geminally installing the oxo and amino groups on the sulfur atom of arenethiols. The products have been primarily developed as sulfinylation reagents to convert Grignard reagents into sulfoxides, and as amination reagents to convert secondary amines into hydrazine derivatives.

Simple and efficient synthesis of 3,4-dihydro-2-pyridones via novel solid-supported aza-annulation

A diverse array of 3,4-dihydro-2-pyridones 13 were produced utilizing the unique properties of solid-supported reactions to both drive the reactions to completion and isolate the desired products. The pyridones were synthesized in high purity by a simple sequence of novel steps commencing from an acetophenone-functionalized resin. The para-substituted acetophenone 9 could be anchored to the resin through either a sulfonamide or a carboxamide linkage. The sulfonamide resin 9a, which gave the best results, was treated with several aryl aldehydes and ethoxide to give a variety of chalcones 10a-k in excellent yield (82-99%) upon TFA cleavage. Addition of either methyl or allyl malonate and DBU to 10a-k afforded smoothly the Michael adducts 11a-j (70-99%) which were subsequently cyclized in one step employing acetic acid as a catalyst and several diverse amines to give pure 3,4-dihydro-2-pyridones 13a-p in moderate to excellent yields (30-98%).
