Biomimetic Synthesis of Tropinone by Oxidation of Hygrine with Mercury(II) Acetate

Tropinone and (E)-2,1'-dehydrohygrine were obtained by refluxing a solution of hygrine in dilute acetic acid with mercury(II) acetate.

THE APPLICATION OF THE SULPHIDE CONTRACTION TO THE SYNTHESIS OF SOME SIMPLE PYRROLIDINE ALKALOIDS

The alkaloids (+/-)-hygrine, (+/-)-dehydrodarlinine, (+/-)-dehydrodarlingianine, and (+/-)-N-methylruspolinone have been synthesised by selective reduction of vinylogous amides formed by sulphide contraction of the salts prepared by reaction of N-methyl-2

Methods for Converting N-Alkyl Lactams to Vinylogous Urethanes and Vinylogous Amides via (Methylthio)alkylideniminium Salts

Treatment of enolizable (methylthio)alkylideniminium salts with active methylene compounds under basic conditions gives Knoevenagel-type adducts in excellent yields.Attempts to convert several of these adducts to vinylogous urethanes and vinylogous amides met with varied success.One-pot preparations of vinylogous urethanes and vinylogous amides from (methylthio)alkylideniminium salts and selected active methylene compounds are also described.
