Multi-Component Reaction of Amines, Alkyl Propiolates, and Ninhydrin: An Efficient Protocol for the Synthesis of Tetrahydro-dihydroxy-oxoindeno[1,2-<i>b</i>]pyrrole Derivatives
A new protocol for the synthesis of a series of tetrahydrodihydroxy-oxoindeno[1,2-b]pyrrolefrom simple primaryamines, alkyl propiolates, and ninhydrin was developed. The key step in the synthesis is an efficient three-component reaction of an amine with an alkyl propiolate to give a 3-amino acrylate derivative, which then reacts with ninhydrin.
