The first enantioselective total synthesis of (S)-equol is reported. The described route relies on an Evans alkylation to form the stereocenter and an intramolecular Buchwald etherification to generate the chroman ring. Key features of this method include its brevity, its scalability, and the low cost of starting materials.

Two new dibenzazonine alkaloids, neodihydrothebaine and bractazonine were isolated from Papaver bracteatum.Their possible biosynthesis from thebaine is discussed.The structures of both new alkaloids are proven by synthesis.An isomeric dibenzazonine compound was also prepared. - Keywords: Papaver bracteatum; Papaveraceae; alkaloids; dibenzazonines; neodihydrothebaine; bractazonine; biosynthetic pathway; synthesis; 5,6,8,9-tetrahydro-2-methoxy-7-methyl-dibenzazonin-1,12-diol; 5,6,8,9-tetrahydro-2,10-dimethoxy-7-methyl-dibenzazonin-1-ol; 5,6,8,9-tetrahydro-2,11-dimethoxy-7-methyl-dibenz-azonin-1-ol; 5,6,8,9-tetrahydro-2,12-dimethoxy-7-methyl-dibenzazonin-1-ol.
