Abstract
•Four new self-assembled phosphorus ligands were synthesized.•Homo-allylic olefin was directly used in tandem hydroformylation–Wittig reaction.•Two more carbon 7-hydroxy enoates were formed in one step.•The diastereoselectivity of β-pyran produced by oxa-Michael reaction was up to 99%.
New self-assembled phosphorus ligands are synthesized and used in the rhodium complex catalyzed hydroformylation–Wittig reaction of homoallylic olefins under optimized condition. A subsequent oxa-Michael intramolecular reaction yields β-pyran derivatives (conversion and diastereoselectivity up to 99%).
