A Chan-Evans-Lam approach to trisubstituted vinyl ethers

Trisubstituted vinyl ethers were accessedviaChan-Evans-Lam coupling of vinyl trifluoroborates and primary aliphatic alcohols. This approach complements prior methods that required the use of neat liquid alcohol coupling partners. A palladium-catalyzed redox-relay Heck reaction was used to convert several vinyl ethers into aldehyde-functionalized 1,3-dihydroisobenzofurans.

Carboxylate-Assisted Oxidative Addition to Aminoalkyl PdII Complexes: C(sp3)?H Arylation of Alkylamines by Distinct PdII/PdIV Pathway

Reported is the discovery of an approach to functionalize secondary alkylamines using 2-halobenzoic acids as aryl-transfer reagents. These reagents promote an unusually mild carboxylate-assisted oxidative addition to alkylamine-derived palladacycles. In the presence of AgI salts, a decarboxylative C(sp3)?C(sp2) bond reductive elimination leads to γ-aryl secondary alkylamines and renders the carboxylate motif a traceless directing group. Stoichiometric mechanistic studies were effectively translated to a Pd-catalyzed γ-C(sp3)?H arylation process for secondary alkylamines.

Synthesis of 9,10-Diarylanthracenes via Mg(TMP) 2 ·2LiCl-Mediated Benzyne Generation/[4+2] Cycloaddition and Deoxygenation of 9,10-Epoxyanthracene Intermediates

A new synthetic route to functionalized 9,10-diarylanthracenes has been developed. 9,10-Epoxyanthracene intermediates were prepared by [4+2] cycloaddition of 1,3-diarylisobenzofuran with a variety of functionalized benzyne intermediates, which were obtained by Mg(TMP) 2 ·2LiCl-mediated benzyne generation. For the cleavage of the resultant 9,10-epoxyanthracene intermediates, we developed mild deoxygenation conditions using a combination of trifluoroacetic acid and Et 3 SiH. The utility of this sequence was demonstrated by application to the synthesis of 5,7,12,14-tetraphenylpentacene.
