Radical heterocyclizations triggered by electron transfer to amide‐type carbonyls, using SmI2‐H2O, provide straightforward access to bicyclic heterocyclic scaffolds containing bridgehead nitrogen centers. Furthermore, the first radical heterocyclization cascade triggered by reduction of amide‐type carbonyls delivers novel, complex tetracyclic architectures containing five contiguous stereocenters with

The copper‐catalyzed intramolecular diastereoselective trifluoromethylcycloetherification of homoallylic alcohols with Togni’s reagent as trifluoromethylating reagent was realized under mild conditions. Various trifluoromethylated tetrahydrofurans were synthesized in moderate to good yields. Moreover, a wide range of common functional groups was tolerated.

Thermal decomposition of methyl aryl cyclopropylcarbinyl borates, followed by hydrolysis, gives rise to mixtures of 1-aryl-1-cyclopropylethylene, and of 4-aryl-3-pentenol. Similarly, aryl cyclopropylcarbinylborates yield trans-4-aryl-3-butenols, while dicyclopropyl carbinyl borate gives a mixture of trans- and cis-4-cyclopropyl-3-butenols.

Copper-catalyzed cross-coupling reactions of vinyl epoxide with arylboronates to obtain aryl-substituted homoallylic alcohols are described. The reaction selectivity was different to that of previously reported vinyl epoxide ring-opening reactions using aryl nucleophiles. The reaction proceeded under mild conditions, affording aryl-substituted homoallylic alcohols with high selectivity and in good
