Exploring the synthetic versatility of the lewis acid induced decomposition reaction of α-diazo-β-hydroxy esters. the case of ethyl diazo(3-hydroxy-2-oxo-2,3-dihydro-1 H-indol-3-yl)acetate
Ethyl diazo(3-hydroxy-2-oxo-2,3-dihydro-1H-indol-3-yl)acetate was prepared by aldol-type condensation of ethyl diazoacetate with isatin. A systematic and mechanistic study on the Lewis acid induced decomposition reaction of this valuable diazo precursor w
