Herein we employed ethynylethylene carbonates (EECs) to achieve formal [4 + 1] and [3 3] cycloaddition with cyclic 1,3-dicarbonyl compounds. On one hand, EECs styryl substitution could undergo a remotely controlled enantioselective reaction. This reaction exhibits good chemoselectivity, regioselectivity, enantioselectivity. In addition, of compounds was also achieved, leading series 4H-pyrans impressive chemoselectivity

The development of efficient and straightforward strategies for obtaining chiral complex molecules from readily available starting materials is great value in drug discovery. stereodivergent synthesis heterocycles bearing quaternary centers remains a challenge due to inherent steric issues. Herein, we report an enantioselective copper-catalyzed decarboxylative [3 + 2] cycloaddition propargyl cyclic carbonates/carbamates with 4-hydroxycoumarins afford wide range dihydrofuro[3,2-

Abstract Optically active molecule architectures stand as an important class of organic compounds and occupy a key role in academic industrial communities. Particularly, the molecules bearing quaternary carbon are vital importance because its favorable conformation valuable three‐dimensional molecules, which frequently play broad spectrum functional materials, pharmaceutical relevant natural agrochemicals. Over past few decades, large number synthetic strategies for enantioselective construction with chiral centers have been focus research initiatives. In this review, state‐of‐the‐art toward synthesis enantioenriched stereocenters summarized, could be segmented into four categories: 1) Construction optically by addition to prochiral sp 2 carbon; 2) all‐carbon via substitution at non‐chiral tetra‐substituted 3) kinetic resolution; 4) desymmetrization reactions.
