Li, Kai;Huang, Shengli;Liu, Tianyu;Jia, Shiqi;Yan, Hailong research published 《 Organocatalytic Asymmetric Dearomatizing Hetero-Diels-Alder Reaction of Nonactivated Arenes》, the research content is summarized as follows. Nonactivated arenes, such as benzene derivatives, are chem. inert due to their intrinsic aromaticity and low polarity. The catalytic asym. dearomatization (CADA, coined by You and co-workers) of the nonactivated arenes represents a formidable challenge. Herein, the authors demonstrate an organocatalytic asym. dearomatizing hetero-Diels-Alder reaction of benzene derivatives The tunable regioselectivity of this strategy allowed delivery of a diversity of stereochem. complex polycyclic compounds, e.g., I, and oxahelicenes, e.g., II, with excellent stereoselectivity. The high complexity and three-dimensionality of the products were crucial for their potential applications in materials science and drug discovery. Mechanistic studies suggested that this reaction proceeded through a chiral tetra-substituted vinylidene ortho-quinone methide (VQM) intermediate, which was extremely active to overcome the loss of aromaticity of benzene derivatives with concomitant chirality transfer.
