An efficient enantioselective construction of tetrahydronaphthalene-1,4-diones as well as dihydronaphthalene-1,4-diols by a chiral phosphoric acid catalyzed quinone Diels-Alder reaction with dienecarbamates is reported. The nature of the protecting group on the diene is key to the success of achieving high enantioselectivity. The divergent "redox" selectivity is controlled by using an adequate amount
据报道,通过手性磷酸催化的二烯氨基甲酸酯的醌Diels-Alder反应,可以有效地对四氢萘-1,4-二酮和二氢萘-1,4-二醇进行对映选择性构建。二烯上保护基的性质是成功实现高对映选择性的关键。通过使用足够量的醌来控制发散的“氧化还原”选择性。单个氧化还原异构体可以在不破坏对映选择性的情况下进行可逆的氧化还原转换。
