- A de Novo Synthetic Route to 1,2,3,4-Tetrahydroisoquinoline Derivatives
-
A novel synthetic approach was developed for the construction of the 1,2,3,4-tetrahydroisoquinoline framework possessing varied functions. The synthetic strategy was based on oxidative ring opening of some indene derivatives through their C=C bond, followed by double reductive amination of the dicarbonyl intermediates with various primary alkyl- or fluoroalkylamines.

- Rearrangements of N-ethoxycarbonylmethyl-1,2,3,4-tetrahydroquinolinium halogenalkylates effected by sodium hydride. Synthesis of 2,3,4,5-tetrahydro-1H- 3-benzazepines
-
Quaternary salts obtained from N-alkyl-1,2,3,4-tetrahydroisoquinolines and ethyl haloacetates or diethyl bromomalonate under the action of sodium hydride in boiling 1,4-dioxane were converted into N-alkyl-N-ethoxycarbonyl-2,3,4,5- tetrahydro-1H-3-benzazep

- Unexpected alkylation reaction of amines, acids and phenols by alkyl (triphenylphosphoranylidene)acetates
-
Reaction of methyl (triphenylphosphoranylidene)acetate in methanol with primary and secondary amines led to N-methylated derivatives. Similarly this mixture reacted with acids, phenol and phthalimide to afford methyl esters, anisole and N-methylphthalimide respectively. Treatment of ketolactam 2 by this mixture under high pressure activation gave the rearranged quinolinone 5.

- A Convenient Preparation of N-Acyl-1,2-dihydroquinoline
-
N-Acetyl- and N-formyl-1,2-dihydroquinolone were conviniently prepared by reductive acylation of quinoline without isolating the labile 1,2-dihydroquinoline.This method was also applied to isoquinoline to prepare N-acetyl-1,2-dihydroisoquinoline.
