Cross-dehydrogenative coupling of dithiolanes with ketones and indoles under metal-free conditions

A metal-free cross-dehydrogenative coupling of dithiolanes with ketones and indoles has been developed using DDQ as an oxidant. It provides an economical protocol for the synthesis of β-keto dithiolanes and 3-(1,3-dithiolan-2-yl) indoles. Georg Thieme Verlag Stuttgart, New York.

1,3-Dithienium- and 1,3-Dithiolenium Salts, II. Synthesis of Monocyclothioacetalized 1,3-Diketones from Silyl Enol Ethers

The 1,3-dithienium and 1,3-dithiolenium salts 3, available from the dithiols 1 or the cyclic thioacetals 4 (n=2, 3) by reaction with the acyl chlorides 2, trityl tetrafluoroborate (5), and sulfuryl chloride (7), react in good yields with the silyl enol ethers 10 to give the new monocyclothioacetalized 1,3-diketones 11.The synthetic potential of 11 as partially protected 1,3-diketones is demonstrated exemplarily by dethioacetalization to the 1,3-dicarbonyl compounds 13.
