A thermal dehydrogenative Diels-Alder reaction of styrenes for the concise synthesis of functionalized naphthalenes.
Functionalized naphthalenes are valuable building blocks in many important areas. A microwave-assisted, intramolecular dehydrogenative Diels-Alder reaction of styrenyl derivatives to provide cyclopenta[b]naphthalene substructures not previously accessible using existing synthetic methods is described. The synthetic utility of these uniquely functionalized naphthalenes was demonstrated by a sing...
متن کاملSynthesis of α-sulfenyl monoketones via a metal-free oxidative cross dehydrogenative coupling (CDC) reaction.
α-Sulfenyl ketones are potential precursors which find a variety of applications in organic synthesis. Their typical synthesis requires pre-functionalized starting materials and two to three step synthetic sequences. In addition, the selective pre-functionalization of unsymmetrical ketones is a challenge, which limits the synthesis of the desired sulfenylated ketones. To overcome these disadvan...
متن کاملManganese-catalyzed aerobic dehydrogenative cyclization toward ring-fused indole skeletons.
We describe the first example of manganese(III)-catalyzed aerobic dehydrogenative cyclization producing ring-fused indole skeletons. This catalytic system converts from two C-H bonds of indole and malonate to a C-C bond and produces water as the sole side product. This operationally easy method was extended to an intermolecular cross-dehydrogenative coupling of indole and α-substituted malonate...
متن کاملA green synthesis of functionalized thiazol-2(3H)-imine via a three-component tandem reaction in ionic liquid media
In this research, an efficient synthesis toward 2-(2-((4-Methoxybenzoyl)imino)-4-(4-methoxyphenyl)thiazol-3(2H)-yl)-2-phenylacetic acid via a three-component tandem reaction using aroylisothiocyanate, phenyl glycine, and 4-methoxyphenacyl bromide in an ionic liquid (IL) has been described. 1-Methyl-3-pentylimidazolium bromide (IL) has been employed as a recyclable green solvent. The work-up pro...
متن کاملUrea-hydrogen peroxide/silica phosphoric acid-catalyzed oxidation- condensation Tandem reaction: One-pot synthesis of 2-substituted benzimidazoles from alcohols
An efficient one-pot oxidation/condensation tandem process has been developed for the synthesis of 2-substituted benzimidazole derivatives from benzylic alcohols and 1,2-phenylenediamine with use of urea-hydrogen peroxide/silica phosphoric acid as a bifunctional catalyst. This method provides a rapid and efficient access to 2-substituted benzimidazoles.
