Tert -Butyl Hypochlorite Mediated Oxidative Chlorination of S -Alkylisothiourea Salts: Synthesis of Sulfonyl Chlorides

Under neutral conditions, a variety of S-alkylisothiourea salts were smoothly converted into the corresponding sulfonyl chlorides through tert-butyl chlorite mediated oxidative chlorination in good to excellent yields after simple purification. In addition to the environmental and procedural advantages of this method, the neutral conditions potentially make it applicable to substrates that bear acid-sensitive functional groups. For example, the Cbz-protected 2-aminoethanesulfonyl chloride could be synthesized in moderate to good yields under the current neutral conditions, and the acid-sensitive Cbz-protecting group was not affected.

A simple method to synthesize diverse sulfonyl chlorides through NaClO 2-mediated oxidative chlorosulfonation of S-alkyl isothiourea salts is presented. The approach features safe operation, environmental friendliness, convenient purification procedures, and delivers high yields of up to 96%. The procedure is also applicable to substrates such as thiols, disulfides, thioacetates, and xanthates. It is a versatile and convenient method for the synthesis of various sulfonyl chlorides from different thiol precursors and derivatives. Georg Thieme Verlag Stuttgart, New York.
