Benzofurans or isochromenes via the ring-opening cyclization of cyclopropene derivatives with organolithiums.
نویسندگان
چکیده
A new and efficient approach to benzocycles from cyclopropene derivatives is described. Deprotection by organolithiums and subsequent ring-opening cyclization of the related 2-cyclopropenyl phenyl or benzyl acetates generated benzofurans and isochromenes in one pot.

Stereoselective Synthesis of 2-(2-Aminoalkyl)- and 1,3-Disubstituted Tetrahydro-1H-pyrido[4,3-b]- Benzofuran and Indole Derivatives.
The addition of an allenyl indium intermediate to chiral N-tert-butanesulfinyl imines 7 proceeds with high levels of diastereocontrol. The resulting homopropargylic amine derivatives 10 were transformed into 2-(2-aminoalkyl)benzofuran and indole derivatives 13 and 19, after Sonogashira coupling with o-iodophenol or o-iodoaniline, followed by formation of the heteroaromatic ring through an intra...
متن کاملFuran ring opening-pyrrole ring closure: a new synthetic route to aryl(heteroaryl)-annulated pyrrolo[1,2-a][1,4]diazepines.
A method of synthesis of pyrrolo[1,2-a][1,4]benzodiazepines is described. This method is based on the recyclization of N-(furfuryl)anthranilamides under treatment with an aq. HCl/AcOH system and allows one to form both diazepine and pyrrole rings in one step. The reaction proceeds via furan ring opening into a diketone moiety followed by consecutive interaction of the NH(2)-group with both carb...

A transition metal-catalyzed cross-coupling reaction of cyclopropenes with aryl iodides proceeds with the opening of the cyclopropene ring, affording 1,3-butadienes as the products.
متن کاملSynthesis of indoles, benzofurans, and related heterocycles via an acetylene-activated SNAr/intramolecular cyclization cascade sequence in water or DMSO.
The synthesis of 2-substituted indoles and benzofurans was achieved by nucleophilic aromatic substitution, followed by subsequent 5-endo-dig cyclization between the nucleophile and an ortho acetylene. The acetylene serves the dual role of the electron withdrawing group to activate the substrate for SNAr, and the C1-C2 carbon scaffold for the newly formed 5-membered heteroaromatic ring. This met...
متن کاملMass spectrometry of derivatives of cyclopropene fatty acids.
Diketo fatty acids prepared by ozonization of cyclopropene fatty acids have been separated and purified by chromatographic techniques. Mass spectra of esters of these compounds and of methanethiol adducts of cyclopropene acid esters are reported and interpreted. Location of the ring from examination of mass spectra of these derivatives appears to be a straightforward matter.
