Highly Regioselective Synthesis of 1,3-Diiodonaphthalene Derivatives via a Sequential Cascade Iodocyclization
摘要:
A novel and flexible sequentially cascade iodocyclization for the synthesis of highly substituted 1,3-diiodinated naphthalene derivatives in up to 99% yield under mild conditions is reported. The dihalogenated moiety can be readily introduced into the naphthalenes in a position that is usually not easily functionalized.
An effective method for alkoxycarbonylation of (hetero)aryl bromides is developed in the presence of in situ-generated phosphinite ligands tBu2POR (R = nBu, nPr, Et or Me). For this purpose commercially available tBu2PCl was used as the pre-ligand in the presence of different alcohols. For the first time cross coupling reactions with two alcohols – one generating the ligand, the other used as substrate
在原位生成的次膦酸酯配体t Bu 2 POR(R = n Bu,n Pr,Et或Me)存在下,开发了一种用于(杂)芳基溴的烷氧羰基化的有效方法。为此目的,在不同醇存在下,将可商购的t Bu 2 PC1用作预配体。首次开发了与两种醇的交叉偶联反应-一种生成配体,另一种用作底物。通过这种方法,可以以更有效的方式进行配体优化,并且可以以良好的产率和选择性获得所需的产物。
