Cotarnic acid

Cotarnine with methyl iodide furnishes cotarnine hydriodide and cotarnine methine methiodide, CiiHu04NMe3l (IX), which is decomposed by alkalis into trimethylamine and cotarnone (X), CuHioO, rhombic plates, m.p. 78°. The latter yields an oxime, m.p. 130-2°, and is oxidised by potassium permanganate to a mixture of cotarnic acid (VI) and cotamlactone, CuHjqOj (XI), brilliant leaflets, m.p. 154°, which is convertible into the corresponding acid, cotarnonelactone acid, leaflets, m.p. 90-100° dec.). The lactone on further oxjdiltion yields cotarnic aeid. ... [Pg.202]
