Seven-membered rings through metal-free rearrangement mediated by hypervalent iodine.
A versatile and metal-free approach for the synthesis of carbocycles and of heterocycles bearing seven- and eight-membered rings is described. The strategy is based on ring expansion of 1-vinylcycloalkanols (or the corresponding silyl or methyl ether) mediated by the hypervalent iodine reagent HTIB (PhI(OH)OTs). Reaction conditions can be easily adjusted to give ring expansion products bearing ...
متن کاملHypervalent Iodine Reagents in High Valent Transition Metal Chemistry.
Over the last 20 years, high valent metal complexes have evolved from mere curiosities to being at the forefront of modern catalytic method development. This approach has enabled transformations complimentary to those possible via traditional manifolds, most prominently carbon-heteroatom bond formation. Key to the advancement of this chemistry has been the identification of oxidants that are ca...
متن کاملTransition metal-free intramolecular regioselective couplings of aliphatic and aromatic C-H bonds
Cross-dehydrogenative couplings of two different C-H bonds have emerged as an attractive goal in organic synthesis. However, achieving regioselective C-H activation is a great challenge because C-H bonds are ubiquitous in organic compounds. Actually, the regioselective couplings promoted by enzymes are a common occurrence in nature. Herein, we have developed simple, efficient and general transi...

متن کاملTransition-metal-free oxidative trifluoromethylation of unsymmetrical biaryls with trifluoromethanesulfinate.
A transition-metal-free direct oxidative trifluoromethylation of unsymmetrical biaryls has been achieved by the simple combination of trifluoromethanesulfinate and phenyliodine bis(trifluoroacetate). The trifluoromethylation is selectively observed in the electron-rich arenes.
