Abstract [en]
2,2′-Biindolyl has been condensed with aromatic and aliphatic aldehydes and products featuring 10-membered rings have been obtained. Thus, benzaldehyde gave compound 24a as the primary product, which readily underwent transannular oxidative coupling to 25a. The structures of both compounds were confirmed by X-ray crystallography. The product from 2,2′-biindolyl and formaldehyde under strongly acidic conditions was slightly different leading to compound 11, whose structure also was confirmed by X-ray crystallography. In this case, two molecules of 2,2′-biindolyl reacted with six molecules of formaldehyde.
