A new strategy for the direct synthesis of quinazolinones from o‐aminobenzonitriles was proposed and accomplished. In the presence of [Cp*IrCl2]2 (Cp*=pentamethylcyclopentadienyl), a variety of desirable products was obtained easily through the one‐pot sequential selective hydration/condensation/acceptorless dehydrogenation. This protocol is highly attractive because it uses readily available starting
Divergent Synthesis of Quinazolin-4(3<i>H</i>)-ones and Tryptanthrins Enabled by a <i>tert</i>-Butyl Hydroperoxide/K<sub>3</sub>PO<sub>4</sub>-Promoted Oxidative Cyclization of Isatins at Room Temperature
hydroperoxide/K3PO4-promoted oxidative cyclization has been developed for the facile synthesis of various functionalized quinazolin-4(3H)-ones from commercially available isatins and amidine hydrochlorides at room temperature. The synthetic utility of this strategy was illustrated by the convenientsynthesis of tryptanthrin derivatives via a self-dimerization of isatins under the same conditions.
已经开发了一种协同作用的叔丁基过氧化氢/ K 3 PO 4促进的氧化环化反应,用于在室温下容易地从市售的靛红和盐酸am合成各种功能化的喹唑啉-4(3 H)-。该策略的合成效用通过在相同条件下通过靛红素的自二聚而方便地合成色胺酮衍生物来说明。
