Opportunities for insiders: A catalytic pinacol-type reductive rearrangement of 1,2-internal diols was developed by the use of a simple boron catalyst and two silanes (see scheme). The reaction occurs through a concerted, stereoinvertive mechanism and is applicable to several substrate scaffolds not usually amenable to pinacol-type reactions, such as aliphatic secondary–secondary diols, without the
内部人士的机会:通过使用简单的硼催化剂和两种硅烷(参见方案),开发了1,2-内部二醇催化的频哪醇型还原重排。该反应通过协同的立体反转机制发生,可用于通常不适合频哪醇类反应的几种底物支架,例如脂族仲-仲二醇,而无需进行预功能化。
