Diastereo- and Enantioselective Carbolithiation of Allyl <i>o</i>-Lithioaryl Ethers. New Chiral Cyclopropane Derivatives
作者:José Barluenga、Francisco J. Fañanás、Roberto Sanz、César Marcos
DOI:10.1021/ol026078x
日期:2002.6.1
[reaction: see text] Different allyl 2-lithioaryl ethers undergo a tandem carbolithiation/gamma-elimination in Et(2)O/TMEDA affording o-cyclopropyl phenol or naphthol derivatives in a diastereoselective manner. The use of (-)-sparteine as a chiral ligand instead of TMEDA allows the synthesis of cyclopropane derivatives with up 81% ee.
On the Reactivity of <i>o</i>-Lithioaryl Ethers: Tandem Anion Translocation and Wittig Rearrangement
