, p. 7925 - 7928 (2001)
An efficient method for the preparation of 3-arylsalicylaldehydes by palladium-catalyzed cross-coupling reaction of arylboronic acids and 3-bromo-5-tert-butylsalicylaldehyde is described. Parallel catalyst screening allowed rapid optimization of the reaction conditions.

supporting information, p. 1553 - 1556 (2020/02/13)
An enantioselective (3+2) cycloaddition of enals and cyclic N-sulfonyl trifluoromethyl ketimines via N-heterocyclic carbene-catalyzed homoenolate addition is described. This reaction can efficiently construct fused N-heterocycle γ-lactams bearing two adjacent chiral centers with >20?:?1 dr and 94-99% ee, with one chiral center as a trifluoromethylated α-tetrasubstituted carbon stereocenter.
