Synthesis and Fluorescent Properties of Novel Isoquinoline Derivatives

Molecules, 2019
Isoquinoline derivatives have attracted great interest for their wide biological and fluorescent properties. In the current study, we focused on the synthesis of a series of novel isoquinoline derivatives substituted at position 3 of the heteroaromatic ...

isoQUINOLINE DERIVATIVES. PART III

, 1957
In contrast with the earlier observation (Ghosh and Dutta, this Journal, 1955, 32, 17, 755) that treat­ment of (a-acetamido-β-phenyl)-etbylmethyl ketone and of β-phenyl-substituted analogues with POCI3 or conc. H2SO4 leads to the formation of I-methylisoquinoline derivatives, accompanied with dehy­drogenation and deacetylation, (α-scetamido-β-phenyl ...

TRANSFORMATION OF 2-BENZOYLAMINO-1-(?-NAPHTHYL)PROPAN-1-OL INTO 4-METHYL-1-PHENYL BENZO[f] ISOQUINOLINE RATHER THAN ITS 3-SUBSTITUTED ISOMER [PDF]

Journal of Sciences, Islamic Republic of Iran, 2001
The necessary conditions to transform hydroxyamide (1) and 2-oxazolines (2, 3) into 3- or 4-methyl benzo[f] isoquinolines (4, 5) has been established. The mechanism of these reactions has been proposed claiming the existence of the protonated 2-oxazoline
