Description

The base-initiated alkylation of the abundant natural dye indigo 1 with ring-strained electrophiles results in the unprecedented, one-pot synthesis of functionalised dihydropyrazino[1,2-a:4,3-a]diindoles, dihydroepoxy[1,5]oxazocino[5,4-a:3,2-b]diindoles, and dihydrodiazepino[1,2-a:4,3-a]diindoles, resulting from intramolecular ring opening-expansion cyclisation processes of their parent oxiranes and aziridines. Regiochemical and stereochemical aspects of the reactions are reported together with...[Show more]
