Retro iminonitroso Diels-Alder reactions were investigated in both solution and solid phase. In thermal or Cu(I)-mediated reactions, interconversion of various nitroso cycloadducts occurred in the presence of separate dienes. Up to 99% of conversion was observed. Use of chiral ligands in the Cu(I)-medicated reactions gave new cycloadducts enantioselectively.
对逆亚胺基亚硝基狄尔斯-阿尔德反应在溶液和固相中都进行了研究。在热反应或铜(I)介导的反应中,各种亚硝基环加合物在单独的二烯存在下会发生相互转化。观察到转化率高达99%。在铜(I)介导的反应中使用手性配体会对映选择性地生成新的环加合物。
