Chemo- And regioselective ring-opening of donor-acceptor oxiranes with: N -heteroaromatics

The first ring-opening of D-A oxiranes with N-heteroaromatics in a chemoselective C-C bond cleavage manner was achieved. In the presence of 5 mol% of Y(OTf)3 as the catalyst, diverse N-heteroaromatics, including benzotriazoles, purines, substituted benzim

Synthesis of chiral tetrahydrofurans via catalytic asymmetric [3 + 2] cycloaddition of heterosubstituted alkenes with oxiranes

An efficient diastereo- and enantioselective [3 + 2] cycloaddition of heterosubstituted alkenes with oxiranes via selective C-C bond cleavage of epoxides has been developed. The reaction was catalyzed by a chiral N,N′-dioxide/Ni(II) catalyst, and a variety of chiral highly substituted tetrahydrofurans were obtained in up to 99% yield, 92/8 dr, and 99% ee.

Tribenzotriquinacene: A versatile synthesis and C3-chiral platforms

Fusing rings: A new synthesis of the bowl-shaped hydrocarbon tribenzotriquinacene is presented (see scheme). The synthesis allows easy access to ortho-functionalized and C3-chiral derivatives that are attractive for supramolecular chemistry and
