Indoles from 3-nitropyridinium salts: A new route to chiral indoles and indolines
摘要:
(S)-1-(1-Methylbenzyl)-2,4,6-trimethylindole was prepared by interaction of (S)isopropyliden(1-methylbenzyl)amine with 1,2,4,6-tetramethyl-3-nitropyridinium iodide. The indoles thus prepared undergo diastereoselective hydride reduction and debenzylation to afford chiral (S)-2,4,6-trimethylindoline with high yield and optical purity up to 76%.
Directarylations of indoles and pyrroles with differently substituted diaryliodonium salts were shown to efficiently proceed in the absence of metal catalysts.
在没有金属催化剂的情况下,用不同取代的二芳基碘鎓盐对吲哚和吡咯的直接芳基化显示出有效的进行。
