slow addition with a syringe pump. From a synthetic point of view, the CH insertion of N‐tosylhydrazones can be viewed as reductivecoupling between a CO bond and a CH bond to form a new CC bond, since N‐tosylhydrazones can be readily prepared from carbonylcompounds. This reaction was successfully applied in a concise synthesis of (±)‐pseudoheliotridane.
hetero-Michael reactions among various oxygen, sulfur, and nitrogen nucleophiles and α,β-unsaturated compounds were carried out in the presence of catalytic amounts of o-benzenedisulfonimide as Brønstedacid organocatalyst. The reaction conditions were very mild, and the yields of target products were good. The catalyst was easily recovered and purified, ready to be used in further reactions. This ability
