ChemInform Abstract: Photolysis of Chloroacetamides as a Route to New 2,8‐Bridged Isoquinoline Derivatives. X‐Ray Crystal Structure of 8,13‐Dihydro‐2‐methoxy‐4,6‐ethanodibenz(c,f)azonine‐5,7‐dione.

Abstract

ChemInform Abstract The dibenzoquinolones (I) are reduced and then acylated to give the N-chloroacetyl compounds (IV) which are irradiated to give the bridged cyclization products (V), together with minor amounts of the pentacyclus (VIa). (Intermediates).
