Data on modelling of reactions and reactivity of fluoroalkenes by both ab initio and semiempyrical quantum-chemical methods are surveyed. Along with the isolated molecule approximation, the methods based on the calculation of potential energy surfaces of the reactions and transition states are used....
1a. We first examine the selective epoxidation of alkenes which is an example where the Molecular Transformer is producing the right prediction for the right reason. We then turn to the Diels–Alder reaction, which is a scaffold-building transformation widely used in synthesis. We show that the...
刊名:Journal of the American Chemical Society 2014年第6期 摘要:Highly chemoselective direct reduction of primary, secondary, and tertiary amides to alcohols using SmI_2/amine/H_2O is reported. The reaction proceeds with C-N bond cleavage in the carbinolamine intermediate, shows...
Quite recently some Cu-, Mn- and Ni-dependent enzymes have been identified for this reaction. This review gives an overview of the different chemical and enzymatic methods available for the cleavage of alkenes.doi:10.1002/adsc.201300882Rajagopalan, Aashrita...
Enantioselective Heck/Tsuji−Trost reaction of flexible vinylic halides with 1,3-dienes The implementation of asymmetric Heck/cross coupling cascades of highly flexible haloalkene substrates remains a challenging and long-standing goal. Here the authors report an asymmetric domino Heck/Tsuji−Trost re...
