Robertson, Alexander; Sandrock, Wm. F. published the artcile< Constituents of Filix mas. II. Synthesis of filicinic acid>, Formula: C19H34O2, the main research area is .
Partial hydrolysis of Me2C(CO2Et)2 gives the acid ester, b6 114-16°, b12 135-6°; PCl5 gives the acid chloride, b19 74-8° (anilide, m. 47-8°); with the Na derivative of CO(CH2CO2Et)2 there results Et 1,1-dimethylpentane-2,4-dione-1,3,5-tricarboxylate, yellow, b5 175-80°; ring closure with EtONa gives Et 1,1-dimethylcyclohexane-2,4,6-trione-3,5-dicarboxylate, m. 147-8°; simultaneous hydrolysis and decarboxylation gives filicinic acid (Boehm, Ann. 329, 289, 321(1903)), which is 1,1-dimethylcyclohexane-2,4,6-trione.
Journal of the Chemical Society published new progress about Ferns. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Formula: C19H34O2.
