Vanadium-Catalyzed Oxidative Intramolecular Coupling of Tethered Phenols: Formation of Phenol-Dienone Products
Gilmartin, Philip H.,Kozlowski, Marisa C.
, p. 2914 - 2919 (2020/04/10)
A mild and efficient method for the vanadium-catalyzed intramolecular coupling of tethered free phenols is described. The corresponding phenol-dienone products are prepared directly in good yields with low catalyst loadings. Electronically diverse tethered phenol precursors are well tolerated, and the catalytic method was effectively applied as the key step in syntheses of three natural products and a synthetically useful morphinan alkaloid precursor.

Structure and synthesis of goudotianine, a new 7-methyldehydroaporphine from Guatteria goudotiana
Castedo,Granja,Rodriguez de Lera,Villaverde
, p. 1561 - 1566 (2007/10/02)
Total synthesis of 2,9-dihydroxy-1,3-dimethoxy-7-methyl-6a,7-dehydroaporphine 1a and 3,9-dihydroxy-1,2-dimethoxy-7-methyl-6a,7-dehydroaporphine 1b are described. Direct comparison of both with natural goudotianine isolated from Guatteria goudotiana R.E. Fries showed the latter to be identical with 1b.
