Abstract

Protocols for preparative (1–80 gram scale) transfer hydrogenations of alkenes over a palladium on carbon catalyst using formic acid/ammonium formate as hydrogen donor are presented. Cinchona alkaloids have been converted to their dihydro derivatives in >94% yield.

Key words

alkaloids - alkenes - catalysis - hydrogen transfer - hydrogenation - palladium

Hydrogenation of the alkaloids in dilute H₂SO₄ with PdCl₂ and H₂ close to regular pressure has been described:

13 Transfer hydrogenation of cinchonine (1 g scale) with a freshly ordered 10% Pd/C catalyst (67 mg, 1:15 ratio; Alfa Aesar) gave a 87% yield within 36 h; with freshly ordered 5% Pd/C catalyst (67 mg, 1:15 ratio; Alfa Aesar), a 94% yield was obtained within 22 h. Thus, the higher metal content did not translate to higher catalytic activity.
