A catalytic tandem olefin migration-aldol condensation process with allylic carbinols and aryl aldehydes was performed with 0.5 mol% of an amphiphilic polystyrene-poly(ethylene glycol) (PS-PEG) resin supported phosphine-ruthenium complex in water as a single reaction medium under heterogeneous conditions to give the corresponding aldols with syn selectivity. Inverse stereoselectivity (anti selectivity) was observed when the reaction was carried out in the presence of KO Georg Thieme Verlag Stuttgart.

An aldol-type and a Mannich-type reaction via the cross-coupling of aldehydes and imines with allylic alcohols catalyzed by RuCl(2)(PPh(3))(3) was developed with ionic liquid as the solvent. The solvent/catalyst system could be reused for at least five times with no loss of reactivity.
