A strong organic base, TBD, functioned as a unique catalyst for the intramolecular multi-step transformation of lactols using the Ferrier-type rearrangement as the key step to provide unsymmetrically substituted 2,2'-dihydroxy biaryl compounds having four ortho substituents about the biaryl axis without the need for a metal catalyst.
强有机碱TBD可作为使用Ferrier型重排的关键步骤进行乳醇分子内多步转化的独特催化剂,该关键步骤是提供不对称取代的2,4'-二羟基联芳基化合物,该化合物在联芳基上具有四个邻位取代基不需要金属催化剂。
