Palladium-catalysed reactions of alcohols. Part B: Formation of C–C and C–N bonds from unsaturated alcohols

“…126). [220][221][222] This intramolecular aminocarbonylation procedure was selective, even from unsaturated aminopolyols (Eq. 127), 223,224 and was extended to N-protected 4-hydroxy-5-hexenylamines.…”

An ionic liquid-tagged second generation Hoveyda–Grubbs ruthenium carbene complex as highly reactive and recyclable catalyst for ring-closing metathesis of di-, tri- and tetrasubstituted dienes

“…After separation of the ionic liquid layer according to the general procedure, the crude product mixture was analyzed by 1 H NMR spectroscopy which revealed a 93:7 ratio between the RCM product 21 and diene 20. Purification by flash column chromatography (hexanes/EtOAc, 5:1 v/v) gave 114 mg (91%) of the known cyclic sulfonamide 21 [6,20].…”
