CRASSIFOLAZONINE, A NEW TYPE OF DIBENZAZONINE ALKALOID

The isolation of crassifolazonine, a dibenzazonine with a new type of tetrasubstitution pattern at 2,3,12,13 positions is described.This is the first example of a dibenzazonine possibly derived from a diphenolic benzylisoquinoline by an ortho-para coupling.

Oxidative Coupling of Phenols and Phenolic Ethers. Part 4. Synthesis of Dibenzazonines and a Dibenzazecine, via Direct Coupling

Two series of amides, N-phenethylphenylacetamides (9) and the bisphenetylamides (11), including diphenolic monophenolic, and non-phenolic types, were treated with a range of one-electron oxidants.With the tetramethoxy-derivative (11e) intramolecular coupling yielded a dibenzazonine (16) in 36percent yield.Similar oxidation of the homologue (18) gave a dibenzazecine (19) in 60percent yield.
