Highly Efficient and General Synthetic Method of Various Retinyl Ethers
Bromination of 4 by PBr3 under Cu(I) catalyst produces the ambidextrous allylic halide 5 regioselectively and stereoselectively. Hetero nucleophiles distinguish the allylic carbon containing Br from the one containing Cl in 5 to give the heteroatom-substituted C5 allylic chloride 3. The Julia olefination reaction with the C15 sulfone 2 provides diverse retinyl ethers 1.
