Alkoxide-Catalyzed Hydrosilylation of Cyclic Imides to Isoquinolines via Tandem Reduction and Rearrangement.

Organic Letters, 2018
An alkoxide-catalyzed hydrosilylation of cyclic imides to isoquinolines was realized via tandem reduction and rearrangement. Using TMSOK as the catalyst and (EtO)2MeSiH as the reductant, a series of cyclic imides containing different functional groups ...

Jet spectroscopy of isoquinoline

Chemical Physics Letters, 1983
The jet-cooled spectra of isoquinoline and an isoquinoline-methanol complex are reported. The lifetimes, dispered fluorescence and excitation spectra are all discussed in terms of excited state interactions. Methanol complexation is found to be a useful probe of excited state level structure and dynamics.

Selective Synthesis of Alkynylated Isoquinolines and Biisoquinolines via RhIII Catalyzed C-H Activation/1,3-Diyne Strategy.

Journal of Organic Chemistry, 2017
Described herein is a convenient and highly selective synthesis of alkynylated isoquinolines and biisoquinolines from various aryl ketone O-pivaloyloxime derivatives and 1,3-diynes via rhodium-catalyzed C-H bond activation.

Isoquinoline and its derivatives

1991
Publisher Summary This chapter covers the chemistry on isoquinoline for the period of 10 years (1985 to 1995). Excellent reviews are published for isoquinoline chemistry, the structure, reactivity, and synthesis of some isoquinolines and hydroisoquinolines that have been reviewed under pyridines and their benzo derivatives in a more concise form in ...

Pictet–Gams isoquinoline synthesis

2002
The isoquinoline framework is derived from the corresponding acyl derivatives of β-hydroxy-β-phenylethylamines. Upon exposure to a dehydrating agent such as phosphorus pentoxide, or phosphorus oxychloride, under reflux and in an inert solvent such as decalin, isoquinoline frameworks are formed.

The reductive alkylation of isoquinoline

Journal of the Chemical Society C: Organic, 1966
Reductive alkylation of isoquinoline with benzaldehyde in acetic acid gives a mixture of 2-benzyl-, 4-benzyl-, and 2,4-dibenzyl-1,2,3,4-tetrahydroisoquinolines and 4-benzylisoquinoline. Contrary to earlier reports, the major product is 2-benzyl-1,2,3,4-tetrahydroisoquinoline, not the 4-isomer.

The Biosynthesis of Isoquinoline Alkaloids

1985
The tetrahydroisoquinoline skeleton occurs in numerous plant alkaloids. The simplest bearers of this structural unit are exemplified by anhalonidine (12) (Sect. 2). Slightly more elaborate are the benzylisoquinoline alkaloids exemplified at their simplest by reticuline (25) and papaverine (27) (Sect. 3).

Isoquinolines in Parkinson’s Disease

2000
1,2,3,4-Tetrahydroisoquinoline (TIQ) derivatives, which chemically resemble MPTP, exist in mammals and have been proposed as candidates for endogenous parkinsonogenic compounds. TIQ, l-benzyl-l,2,3,4-tetrahydroisoquinoline (1-benzyl-TIQ) could induce parkinsonism in rodents and a primate.
