• Practical and Highly Selective CH Functionalization of Structurally Diverse Ethers

  A trityl ion mediated CH functionalization of ethers with a wide range of nucleophiles at ambient temperature has been developed. The reaction displays high chemoselectivity and good functional group tolerance. The protocol also exhibits excellent regio‐ and diastereoselectivities for the unsymmetric ethers, thus stereoselectively generating highly functionalized disubstituted 2,5‐trans tetrahydrofurans

  1-borazaronaphthalene has provided an opportunity to expand dramatically the functionalization of the azaborines. This azaborinyl building block can serve as the electrophile in palladium-catalyzed cross-coupling reactions to form sp3–sp and sp3–sp2 bonds. The cross-coupling reactions of 2-(chloromethyl)-2,1-borazaronaphthalene with potassium (hetero)aryl- and alkenyltrifluoroborates as well as terminal alkynes provides

Under mild metal-free conditions, readily available N-carbamoyl 1,2-dihydroquinolines undergo oxidative C–H alkynylation, alkenylation, and allylation with a range of potassium trifluoroborates using TEMPO oxoammonium salt as an oxidant.

• Expanded Substrate Scope and Improved Reactivity of Ether-Forming Cross-Coupling Reactions of Organotrifluoroborates and Acetals

  Mixed acetals and organotrifluoroborates undergo BF3 center dot OEt2-promoted cross-couplings to give dialkyl ethers under simple, mild conditions. A survey of reaction partners identified a hydroxamate leaving group that improves the regioselectivity and product yield in the BF3 center dot OEt2-promoted coupling reaction of mixed acetals and potassium alkynyl-, alkenyl-, aryl- and heteroaryltrifluoroborates to access substituted dialkyl ethers. This leaving group enables the reaction to proceed rapidly under mild conditions (0 degrees C, 5-60 min) and permits reactions with electron-deficient potassium aryltrifluoroborates that are less reactive with other acetal substrates. A study of the reaction mechanism and characterization of key intermediates by NMR spectroscopy and X-ray crystallography identified a role for the hydroxamate moiety as a reversible leaving group that serves to stabilize the key oxocarbenium intermediate and the need for a slight excess of organodifluoroborane to serve as a catalyst. A secondary role for the boron nucleophile as an activating ligand was also considered. These studies provide the basis for a general class of reagents that lead to dialkyl ethers by a simple, predictable cross-coupling reaction.

  Conditions have been developed for the palladium-catalyzed cross-coupling of 3-bromo-2,1-borazaronaphthalenes with potassium alkenyltrifluoroborates. Twenty-seven alkenyl-substituted azaborines have been synthesized through this method, providing access to a family of 2,1-borazaronaphthalenes with alkenyl substitution at the C3 position.
