An eco-friendly synthesis of cyclic carbonates through a Lewis acid catalyzed cyclization of tert-butyl carbonates is described. These cyclic carbonates are precursors of 1,2- and 1,3-diols, and the developed method was applied to a short synthesis of a diarylheptanoid, (3S,5S)-alpinikatin.

Asymmetric total synthesis of xyolide, a small ring macrolide is presented in this article. The synthesis is achieved through an 'E' selective cross metathesis (CM) reaction between two appropriate fragments followed by lactonization by Shiina method. One of the fragments containing 7S,8S,9R stereocenters of xyolide is accessed from n-nonanal by adopting an organocatalytic asymmetric α-aminooxylation, Z-selective Ando olefination, and substrate directed dihydroxylation reaction. The other fragments containing 4S stereocenter was prepared by ME-DKR (metal enzyme combined dynamic kinetic resolution) method.

A trisubstituted α,β-unsaturated ester moiety was suitably placed in a molecule also bearing an epoxy alcohol moiety at its other end to intramolecularly trap the intermediate radical, which was formed when the molecule was treated with Cp2Ti(I

Although febrifugine (1) and isofebrifugine (2), alkaloids isolated from roots of the Dichroa febrifuga plant, show powerful antimalarial activity against Plasmodium falciparum, strong side effects such as the emetic effect have precluded their clinical u
Stereoselective synthesis of the 2,6-disubstituted tetrahydropyran-3-ol of the potent antitumor agent mucocin via an acyl radical cyclization
Evans, P. Andrew,Roseman, Jamie D.
, p. 5249 - 5252 (2007/10/03)
The intramolecular acyl radical cyclization of the acyl selenide 8, using a Z-vinylogous sulfonate to control rotamer population, affords the cis-2,6-disubstituted tetrahydropyran-4-one 9, applicable to the potent antitumor agent mucocin 1 in 81% yield.
