Sodiumhypochlorite pentahydrate (NaOCl·5H2O) can be used toward the efficient glycol cleavage of trans-cyclic glycols, which are generally resistant to this transformation. Interestingly, the reaction of cis-cyclic glycols with NaOCl·5H2O is slower than that observed for the corresponding trans-isomer. This trans selectivity is in sharp contrast to traditional oxidants used for glycol cleavage. Acyclic
The first syntheses of tri- and tetra-cyclic vic-disubstituted areneoxides are described. The general route to 9,10-dimethyl- and 9,10 - bis(p - chlorophenyl) - phenanthrene - 9,10 - oxide, and to 5,6 - diphenylbenzo[c]phenanthrene 5,6 - oxide, includes oxidation of the unsubstituted aromatic hydrocarbon to the K-region quinone followed by reaction with an alkyl- or aryl-magnesium bromide and treatment
描述了三环和四环维克二取代的芳烃氧化物的第一合成。生成9,10-二甲基-和9,10-双(对氯苯基)-菲-9,10-氧化物和生成5,6-二苯基苯并[ c ]菲5,6-氧化物的一般方法包括氧化将未取代的芳烃加到K-区醌上,然后与烷基或芳基-溴化镁反应,并用二甲基甲酰胺二甲基缩醛处理所得的反式-二醇。先前关于二取代氧化丙烯的合成的报告已被证明是错误的。
Synthesis of functionalized polycyclic compounds via a novel aromatic oxy-Cope rearrangement
Polycyclic compounds have been prepared by aromatic dianionic oxy-Cope rearrangements involving the π bonds of two phenyl rings in a [3,3] sigmatropic rearrangement.
多环化合物已经通过芳族二阴离子氧基-Cope重排制备,该重排涉及两个苯环的[3,3]σ重排的π键。
