Journal ArticleDOI
Site-selective Suzuki–Miyaura reactions of the bis(triflate) of 1,3-dihydroxythioxanthone
TL;DR: The Suzuki cross-coupling reaction of the bis(triflate) of 1,3-dihydroxythioxanthone afforded various aryl-substituted thioxanthones.
Journal ArticleDOI
SmI2-mediated reductive cyclization of β-arylthio ketones: a facile and diastereoselective synthesis of thiochroman derivatives
TL;DR: The results of the current study show that the cyclization also occurs when other substitution patterns are present, affording a general approach to dihydrothiochroman-ols in good yields and high degrees of diastereoselectivity.
Journal ArticleDOI
Synthesis of polysubstituted 3,4-dihydro-2H-thiopyrans by regioselective annulation of 3,3-disubstituted allylic alcohols with a β-oxodithioester
TL;DR: Polyfunctionalized 3,4-dihydro-2H-thiopyrans were obtained in high yields via the regioselective annulation of 3,3-disubstituted allylic alcohols with a β-oxodithioester under BF3·Et2O catalysis as discussed by the authors.
Journal ArticleDOI
The N–H···X Hydrogen Bonds in the Crystal Structures of (Thio)Isochromene Derivatives
TL;DR: In this article, the 6-amino-8-(2,3-dichlorophenyl)-8,8a-dihydro-1H-isothiochromene-5,7,7(3H)- tricarbonitrile DMF solvate was synthesized and characterized by IR, 1H NMR and HRMS.
Journal ArticleDOI
3,5-Dialkyltetrahydro-4 H- thiopyran-4-ones under the conditions of Mannich reaction
TL;DR: In this article, an equilibrium between the chair and boat conformations in the thiopyranone ring was found in CDCl3 solutions of 7-(2-hydroxyethyl)-1,5-dimethyl-3-thia-7-azabicyclo[3.3.1]nonan-9-one at 50°
