of carbonyl groups in keto aldehyde substrates has been exploited for the synthesis of phenanthrols, naphthols, and their heteroatom‐containing analogues. Key to this highly efficient and robust methodology is the catalyst‐free intramolecular formal diazo carbon insertion of N‐tosylhydrazones into keto CC bonds (see scheme).
酮醛底物中两种羰基的不同反应性已被用于合成菲咯啉,萘酚及其含杂原子的类似物。键这一高效完善的方法是的不含催化剂的分子内正式重氮碳插入Ñ -tosylhydrazones成酮Ç C键(参见方案)。
