Nenitzescu indole synthesis pdf

A Nenitzescu reaction has been used to prepare the indole skeleton 6 having all the functional groups necessary for its conversion into 10a, a key intermediate in a short synthesis of the. Sep 15,  · The synthesis of a 5‐hydroxyindole derivative involving the condensation between a 1,4‐benzoquinone and a β‐amino‐α,β‐unsaturated compound and subsequent cyclization is generally known as the Nenitzescu indole synthesis. Abstract: Functionalized indoles are synthezised under mild conditions in a tartaric acid–dimethylurea melt. The melt serves as the solvent and as the catalyst. Under these reaction conditions, sensitive functional groups such as N-Boc, N-Cbz, or azides are stable, Cited by:
