Abstract

As series of (1H-indol-3-yl)phosphonates and bisphosphonates as well as (1H-indol-1-yl)phosphonates and bisphosphonates was prepared via the Michael addition of substituted indoles with electron-deficient olefins like ethyl 2-(diethoxyphosphoryl)acrylate and tetraethyl ethenylidene-1,1-bisphosphonate. The chemoselectivity of the reaction is discussed.
