Stereoselective palladium-catalyzed synthesis of structurally versatile indoline derivatives, using molecular oxygen as the sole oxidant, is described. New C-N and C-C bonds form across an alkene in an intramolecular manner. The C-N bond-forming step proceeds via a syn-amidopalladation pathway. The moderate kinetic isotope effects (intramolecular KIE = 3.56) suggest that electrophilic aromatic substitution occurs in the arylation step.

Three 3-(2-hydroxy-2-methylcyclohexylmethyl)butanolides were synthesized and checked for inotropic activity.Very weak effects were observed for all of them. cardenolide analogues/ butanolides/ inotropic effects
β-hydroxy Esters: (E)- versus (Z)-Enolate Geometry in Dianionic Claisen Rearrangements
Kurth, Mark J.,Beard, Richard L.
, p. 4085 - 4088 (2007/10/02)
Control elements operative in the β-hydroxy ester dianionic Claisen rearrangements are probed.Stereochemistry at Cβ dictates face selectivity at Cα and Cβ' in 1->2-5, but only to the extent that it controls ester enolate g
