Br?nsted Acid Catalyzed Homoconjugate Addition of Organotrifluoroborates to Arylated Cyclopropyl Ketones
Nguyen, Truong N.,Nguyen, Thien S.,May, Jeremy A.
, p. 3786 - 3789 (2016/08/16)
A novel and practical homoconjugate addition of alkenyl, alkynyl, heteroaryl, and aryl trifluoroborates to arylated cyclopropyl ketones to synthesize γ,γ-disubstituted ketones is reported. A preliminary mechanistic proposal involving ketone protonation, a

A novel entry to functionalized benzofurans and indoles from furans in moderate to good yields has been developed. This protocol involves palladium(0)-catalyzed dearomatizing intramolecular arylation of the furan ring, formation of a π-allylic palladium complex, furan ring opening, and a β-hydride elimination sequence.
Enantioselective conjugate addition of alkenylboronic acids to indole-appended enones

supporting information; experimental part, p. 4958 - 4961 (2011/11/29)
An enantioselective addition of alkenylboronic acids and alkynylboronic esters to unprotected indole-appended enones is reported. This transformation proceeds with high enantioselectivity and high product yields via the use of catalytic amounts of 3,3′-bis(pentafluorophenyl)-BINOL and Mg(Ot-Bu) 2. A range of α-branched indole derivatives are available from the transformation.
Diels-Alder reactivity and some synthetic applications of (E)-1-(3-indolyl)-3-tert-butyldimethylsiloxy-1,3-butadienes
Caballero, Esther,Longieras, Nicolas,Zausa, Elodie,Del Rey, Benedicto,Medarde, Manuel,Tomé, Fernando
, p. 7233 - 7236 (2007/10/03)
The preparation of (E)-1-(3-indolyl)-3-tert-butyldimethylsiloxy-1,3-butadienes and their Diels-Alder reaction with selected dienophiles at room temperature is described. The utility of these heteroaryldienes for the construction of different (3-indolyl)-planar systems is shown by the synthesis of a grooved analogue of arcyriaflavin A.
