摘要

In principle, a transition metal catalyst could obviate the need for such reagents and permit the convergent synthesis of sulfonamide analogues, allowing variation of both sulfonyl (−SO 2 −) substituents. Unfortunately, success in this area of catalysis is limited to a single Pd-catalyzed aminosulfonylation process, initially reported by Willis in 2010, to prepare N-amino-sulfonamides (1) from aryl iodides and hydrazines (eq 1).(12) While this example represents an ...
