A new type of binaphthyl-based chiral iodide functionalized at positions 8 and 8′ of the naphthalene rings has been found as a promising structural motif for the asymmetric hypervalent iodine(III) oxidations, specifically, for the dearomatizing spirocyclization of naphthol carboxylic acids showing expectedly better enantioselectivities versus other atropisomeric biaryls, i.e., a conventionally used
已发现在萘环的8和8'位上官能化的新型基于联萘的手性碘化物是不对称高价碘(III)氧化的有前途的结构基序,特别是用于萘酚羧酸的脱芳香环化反应与其他阻转异构联芳基,即常规使用的在小凹槽中具有二碘化物的双萘相比,具有更好的对映选择性。
