Safe from protection! A pronounced kinetic preference for primary alcohol dehydrogenation enables the site‐selective iridium catalyzed CC coupling of polyols with allyl acetate in the absence of protecting groups, premetallated reagents, chiral auxiliaries, and discrete alcohol‐to‐aldehyde oxidation.
安全无保护!伯醇脱氢的显着动力学偏好使得在没有保护基团、预金属化试剂、手性助剂和离散醇到醛氧化的情况下,位点选择性铱催化多元醇与乙酸烯丙酯的C C 偶联成为可能。
