Structure and synthesis of goudotianine, a new 7-methyldehydroaporphine from Guatteria goudotiana

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.
