Chromatography-free Pd-catalyzed deprotection of allyl ethers using PS-DEAM as a scavenger of boronic acids and Pd catalyst

Polystyrene-bound diethanolamine (PS-DEAM) work-up for a newly developed Pd-catalyzed deprotection of allyl ethers using boronic acids can effectively release Pd-free parent alcohols without use of column chromatography.
