conditions and with very good yield by a one-pot synthesis based on a modified oxa-Pictet–Spengler reaction. In this paper, we demonstrate that the above reaction is also useful for the synthesis of hydroxyphthalans, and we discuss the effects of the substituents on the alcoholic aromatic ring on the course of the reaction, as well as those on the aldehydic structure. We also report a synthesis of h
最近,我们报道了 6-羟基和 6,7-二羟基异色满可以在非常温和的条件下通过基于改进的 oxa-Pictet-Spengler 反应的一锅合成获得非常好的收率。在本文中,我们证明了上述反应也可用于合成羟基酞,并讨论了醇芳环上的取代基对反应过程以及醛结构的影响。我们还报告了通过相同方法进行的羟基同色满的合成。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
