摘要：
[GRAPHICS] An unprecedented copper phosphoramidite catalyzed enantioselective alkylative ring-opening reaction of oxabenzonorbornadiene derivatives with dialkylzinc reagents is reported. The reaction shows high levels of ant stereoselectlvity (up to anti/syn >99:1), complementary to the Pd(0)-catalyzed syn-selective ring-opening protocol, allowing a new entry to anti-dihydronaphthols with high enantioselectivity (up to 99% ee).
