An approach to hydrocarbazoles bearing an all-carbon quaternary center at C4a position was developed via a Br?nsted acid-initiated Diels-Alder cycloaddition/retro-aza-Michael addition cascade process from azepino[4,5-b]indoles and commercially available d

(Chemical Equation Presented) A new and efficient synthetic route to chiral 3-substituted hexahydropyrroloindoline 18 possessing absolute configurations in accordance with indole alkaloids has been developed from readily available L-tryptophan. The key step relies on the one-pot cascade reaction of oxazolidinone 17 with diazoester, which proceeds through intermolecular cyclopropanation, ring opening, and cyclization.
