Visible-Light-Promoted Cascade Radical Cyclization: Synthesis of 1,4-Diketones Containing Chroman-4-One Skeletons

A visible-light-induced cascade radical cyclization of aroyl chlorides with 2-(allyloxy)-benzaldehyde derivatives has been developed. The method takes advantages of unactivated C=C bonds as the acyl radical acceptors and offers a mild and green approach for the synthesis of 1,4-diketones bearing biologically important chroman-4-one skeletons with moderate to good yields.

Carbon-Carbon Bond Formation via Intramolecular Cycloadditions: Use of the Thiocarbonyl Ylide Dipole in anhydro-4-Hydroxythiazolium Hydroxides

The mesoionic systems resulting from the introduction of 2-(allyloxy)phenyl substituents into the 2-, 3-, and 5-positions of anhydro-4-hydroxythiazolium hydroxide undergo intramolecular cycloaddition under different reaction conditions, the ease of cycloa

Intramolecular 1,3-Dipolar Cycloaddition with Thiocarbonyl Ylides

anhydro-2-(2-Allyloxyphenyl)-3,5-diphenyl-4-hydroxythiazolium hydroxide and related alkenic systems, together with the corresponding prop-2-ynyloxy and cyanomethyloxy derivatives, undergo ready thermal intramolecular 1,3-dipolar cycloadditions giving stab

New Intramolecular Cycloaddition Reactions of Mesoionic 1,3-Dithiolones

The syntheses and spectroscopic data of the new mesoionic 1,3-dithiolones 4, 5 and 6 are described.As a cyclic thiocarbonyl ylid which contains a non-activated olefinic function in the same molecule 5 yields at 120 deg C the tetracyclic primary adduct 7 (90percent) due to intramolecular cycloaddition.On the other hand, the analogous reaction of 6 produces the thiophene derivative 9 (92-96percent yield) by concomitant evolution of COS from the intramolecular primary adduct 8.
