Oligosaccharide Assisted Approach: An Efficient and Facile Access to Isochromeno [4,3-b] Indoles Derivatives in the Presence of Beta Cyclodextrin
Catalysis Letters(2018)
摘要
A completely eco-friendly and straightforward protocol for the biologically important isochromeno[4,3-b]indoles derivatives has been developed employing beta cyclodextrin in aqueous medium. This documented strategy includes the elimination of hazardous catalysts and volatile organic solvents. Additionally this protocol highlights environmentally benign reaction conditions, short reaction times, operational simplicity, easy workup and purification procedure and good yield of products.
