Synthesis of tetrasubstituted benzenes via rhodium(I)-catalysed ring-opening benzannulation of cyclobutenols with alkynes.
نویسندگان
چکیده
A formal [4 + 2] annulation occurs between 1,3-disubstituted cyclobutenols and internal alkynes in the presence of rhodium(I) catalysts to afford 1,2,3,5-tetrasubstituted benzenes. These benzannulation products are generated through dehydration of the initially formed cyclohexadienols.

Rhenium- and manganese-catalyzed carbon–carbon bond formation using 1,3-dicarbonyl compounds and alkynes*
Abstract: A rhenium complex, [ReBr(CO)3(thf)]2, catalyzed insertion of terminal alkynes into a C–H bond of active methylene sites of 1,3-dicarbonyl compounds. When a catalytic amount of isocyanide or molecular sieves was added to the reaction mixture, the reaction course changed markedly, and insertion of alkynes into a C–C single bond between αand β-positions of cyclic and acyclic β-keto ester...
متن کاملConvergent synthesis of fully functionalized ring C allocolchicinoids. Benzannulation approach.
[reaction: see text]. A novel convergent approach to fully functionalized ring C allocolchicinoids is developed which is based on the benzannulation reaction of Fischer carbene complexes with alkynes. The efficacy of this strategy was established with the conversion of bromide 1a (R1 = Me, R2 = H) to the biaryl phenol 3a (R = Me, R(L) = Pr, R(S) = H) via the carbene complex 2a. Bromide 1b (R1 =...
متن کاملFirst total synthesis of antiostatin A1, a potent carbazole-based naturally occurring antioxidant.
The first total synthesis of the potent antioxidant antiostatin A1 is reported, where its key features rely on a chemo- and regioselective rhodium-catalysed crossed alkyne cyclotrimerisation reaction applying functionalised ynamides and a palladium-catalysed arylamidation reaction.
متن کاملConstruction of tetralin skeletons based on rhodium-catalysed site-selective ring opening of benzocyclobutenols.
Tetralins (tetrahydronaphthalenes) are synthesised from benzocyclobutenols based on the rhodium-catalysed site-selective ring opening followed by intermolecular/intramolecular conjugate addition of the resulting arylrhodium species to electron-deficient alkenes. The produced structures make a remarkable contrast with those available from the same compounds under thermal reaction conditions.
متن کاملRegioselective solvent-dependent benzannulation of conjugated enynes.
The transformation of enynes under cobalt-catalysis leads to symmetrical benzannulation products in dichloromethane. In tetrahydrofuran the cobalt-catalysed reactions afforded the unprecedented unsymmetrical benzannulation products in moderate to good yields and good regioselectivities. In addition, cyclotrimerisation of the alkyne subunit can be realised when electron-deficient enynes are appl...
