“…Both compounds were optically inactive, suggesting that the introduction of the oxygen function at C-3 could have a nonbiogenetic origin. A number of other oxindole alkaloids possessing a 3-hydroxy substituent have been isolated from natural sources, some of which are also mixtures of epimers at C-3, while others are optically active. A small number of these have been synthesised, mostly using isatin ( 3 ) as the starting compound. ,, We now report the first synthesis of donaxaridine using a procedure that does not require protection of the indole nitrogen.…”

“…Análise detalhada dos dados de RMN indicou que a unidade que está ligada à parte cinamoílica corresponde a um sistema trans-1,2-dissubstituído, evidenciado pelos sinais em δ 4,95 dd (J = 1,0; 3,0 Hz), δ 7,01 dt (J = 3,0; 16,0 Hz) e 6,65 dt (J = 16,0; 1,0 Hz) e pelo sinal em δ 2,89 (s) referente a um grupo metílico. Estes dados, analisados em conjunto com aqueles obtidos do espectro de massas, análise elementar e comparação com a literatura 4,8 permitiram concluir que 1 é a substância conhecida trans-cinamato de trans-3'-metilsulfonilalila. Em adição, as análises dos dados espectrais de RMN de 13 C e de HMBC permitiram atribuir de maneira inequívoca os valores dos deslocamentos químicos dos carbonos 4 e 3' dessa substância (Tabela 1) uma vez que, no único registro encontrado na literatura 4 , esses valores foram obtidos por técnicas unidimensionais que não permitiram sua discriminação.…”
