[3 + 2]-Annulations of N-Hydroxy Allenylamines with Nitrosoarenes: One-Pot Synthesis of Substituted Indole Products
摘要:
In the presence of O-2 and an IPrCuCl additive (5 mol %), [3 + 2]-annulation reactions of N-hydroxyaniline with nitrosobenzenes in cold toluene form isoxazolidin-5-ol derivatives. Heating the same reaction mixture with DBU in toluene affords highly functionalized indole products efficiently. This method provides short synthesis of several bioactive molecules including WIN 48098, WIN 53365, and JWH 015.

radiotracers for positronemissiontomography (PET) imaging is of paramount importance, because such a noninvasive imaging technique would allow better understanding of the link between the activity of GSK-3β and central nervous system disorders in living organisms, and it would enable early detection of the enzyme's aberrant activity. Herein, we report the synthesis and biologicalevaluation of a series

versatile 3-acylindoles through Rh(III)-catalyzed C–H activation and annulation cascade of N-phenylamidines with α-Cl ketones was developed, in which α-Cl ketones serve as unusual one-carbon (sp3) synthons. This strategy features high regioselectivity, efficiency, wide substrate tolerance, and mild reaction conditions, which further underscore its synthetic utility in drug molecule synthesis.
