Biomimetic Synthesis of Tropinone by Oxidation of Hygrine with Mercury(II) Acetate
Leete, Edward,Kim, Sung Hoon
, p. 1899 - 1900 (1989)
Tropinone and (E)-2,1'-dehydrohygrine were obtained by refluxing a solution of hygrine in dilute acetic acid with mercury(II) acetate.
A NOVEL DECARBOXYETHYLATION OF ENAMINOESTERS
Rigo, Benoit,Jabre, Samir,Maliar, Frederick,Couturier, Daniel
, p. 473 - 478 (2007/10/02)
A novel procedure for the decarboxylation of enaminoesters by using acidic alumina at 250 deg C is described.
THE APPLICATION OF THE SULPHIDE CONTRACTION TO THE SYNTHESIS OF SOME SIMPLE PYRROLIDINE ALKALOIDS
Ghirlando, Rodolfo,Howard, Arthur S.,Katz, Ruth B.,Michael, Joseph P.
, p. 2879 - 2884 (2007/10/02)
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
Lactam Acetals: Part VI - A Novel Synthesis of 4-Substituted 6,7-Dicarbomethoxy-2,3-dihydro-1-methylindoles
Ahuja, Padma,Singh, Jujhar,Anand, Nitya
, p. 142 - 143 (2007/10/02)
Reaction of 2-(α-alkanoyl/aroyl)methylene-1-methylpyrrolidines (2-5) with dimethyl acetylenedicarboxylate furnishes 4-alkyl/aryl-6,7-dicarbomethoxy-2,3-dihydro-1-methylindoles (6-9).Since 2-5 are readily accessible via condensation of 2,2-dimethoxy-1-methylpyrrolidine (1) with appropriate alkyl or aryl ketones, this transformation constitutes a facile synthesis of polysubstituted indoles.
Methods for Converting N-Alkyl Lactams to Vinylogous Urethanes and Vinylogous Amides via (Methylthio)alkylideniminium Salts
Gugelchuk, Mary M.,Hart, David J.,Tsai, Yeun-Min
, p. 3671 - 3675 (2007/10/02)
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.
