Convergent First Total Synthesis of Melovinone: A Densely Substituted 3-Methoxy-4-quinolone Isolated from Melochia tomentosa L

Arroyo Aguilar, Abel Alfredo; Ledesma, Gabriela Nanci; Tirloni, Bárbara; Kaufman, Teodoro Saul; Larghi, Enrique Leandro (Georg Thieme Verlag Kg, 2019-08)

The first total synthesis of melovinone, a nonrutaceous 3-methoxy-4-quinolone alkaloid isolated from Melochia tomentosa L., is reported. The target was acquired in a convergent fashion through the Suzuki?Miyaura cross-coupling ...

Pozzi, Gustavo C.; Goeta, Andrés Eduardo; Autino, Juan Carlos; Punte, Graciela María del Carmen (2003)

Total Synthesis of Waltherione F, a Nonrutaceous 3-Methoxy-4-quinolone, Isolated from Waltheria indica L. F.

Arroyo Aguilar, Abel Alfredo; Bolivar Avila, Santiago Junior; Kaufman, Teodoro Saul; Larghi, Enrique Leandro (American Chemical Society, 2018-08)

Waltherione F was totally synthesized in seven steps and 31% overall yield from 2-nitro-3-methylanisole without the use of protecting groups. Key steps in the sequence were a Suzuki-Miyaura coupling to attach the n-octyl ...
