Method for synthesizing tetrahydroberberine and derivatives thereof

-

Paragraph 0094-0099, (2021/07/08)

The invention provides a method for synthesizing tetrahydroberberine and derivatives thereof. Specifically, in the presence of an iridium metal catalyst precursor, a chiral diphosphine ligand, an acid and a halogen-containing additive, in a hydrogen atmosphere, a compound (II) is subjected to an asymmetric catalytic hydrogenation reaction in an organic solvent so as to prepare the compound (I).

Asymmetric synthesis of (S)-(-)-tetrahydropalmatine and (S)-(-)-canadine via a sulfinyl-directed Pictet-Spengler cyclization

Mastranzo, Virginia M.,Olivares Romero, José Luis,Yuste, Francisco,Ortiz, Benjamín,Sánchez-Obregón, Rubén,García Ruano, José L.

, p. 1266 - 1271 (2012/02/15)

(S)-(-)-Tetrahydropalmatine 2 and (S)-(-)-canadine 4 were synthesized in three steps from (S)-6, in 33% and 34% overall yield, respectively. Thus, condensation of the (S)-(E)-sulfinylimines 10 and 11 with the carbanion derived from (S)-6 gave the tetrahydroisoquinolines 12 and 13, respectively, which upon TFA induced N-desulfinylation, and subsequent microwave assisted Pictet-Spengler cyclization effected both cyclization and C-desulfinylation producing (S)-(-)-tetrahydropalmatine 2 and (S)-(-)-canadine 4 in optically pure form.
