Multicomponent Reactions with Isocyanides

Angewandte Chemie - International Edition, 2000
Multicomponent reactions (MCRs) are fundamentally different from two-component reactions in several aspects. Among the MCRs, those with isocyanides have developed into popular organic-chemical reactions in the pharmaceutical industry for the preparation of compound libraries of low-molecular druglike compounds.

Isocyanides

2022
Isocyanides are powerful functionalities by virtue of the carbene-like terminal carbon that imparts unique reactivity. Capable of functioning as electrophiles, nucleophiles, radical acceptors, and in transition metal-catalyzed insertions, isocyanides engage in a plethora of methodologies that generate complex molecules from relatively simple starting ...

Fluoromethyl isocyanide and difluoromethyl isocyanide

Journal of Fluorine Chemistry, 1991
Abstract Whereas methyl isocyanide is known since more than a hundred years, the chemistry of its perfluorinated derivative CNCF 3 , has been developed only recently. Both compounds differ drastically. Herein we report the syntheses of the missing partially fluorinated compounds CNCH 2 F and CNCHF 2 via their pentacarbonyl chromium complexes.

Isocyanide insertion reactions. The role of isocyanide insertions in the metal assisted hydrogenation of isocyanides

Journal of the American Chemical Society, 1978
H/sub 2/Os/sub 3/(CO)/sub 10/ was reacted with phenyl isocyanide to form H/sub 2/Os/sub 3/(CO)/sub 10/(CNC/sub 6/H/sub 5/), which upon refluxing loses 1 mol CO to form a new complex that is believed to be a possible intermediate in the phenyl isocyanide reduction process. The molecular structure of the last complex was determined. (DLC)

2,4,6-Trimethylphenyl isocyanide

Acta Crystallographica Section C Crystal Structure Communications, 2002
The title compound, C(10)H(11)N, displays a crystallographic mirror plane that incorporates all the non-H atoms, as well as the H atoms attached to the aromatic ring. The isocyano group is almost linear and shows an N[triple bond]C bond distance of 1.158 (3) A.

Isocyanide-Based Multicomponent Reaction ‘without’ Isocyanides

Synlett, 2009
We present here a one-pot, four-component sequence that affords Ugi-type adducts starting from simple benzyl or allyl bromides. The isocyanides are prepared in situ under alkylation of silver cyanide salts and the resulting mixture is directly used in a Ugi―Smiles coupling.

Palladium‐Catalyzed Migratory Insertion of Isocyanides: An Emerging Platform in Cross‐Coupling Chemistry

Angewandte Chemie - International Edition, 2013
Isocyanides have been important building blocks in organic synthesis since the discovery of the Ugi reaction and related isocyanide-based multicomponent reactions. In the past decade isocyanides have found a new application as versatile

Microchemical detection of isocyanides

Talanta, 1967
Microgram quantities of isocyanides may be easily detected on filter paper or in tubes of silica gel by using benzidine acetate-copper(II) acetate or p,p'-tetramethyldiaminodiphenylmethane-copper(II) sulphate reagents. Interferences include those substances which are known to interfere in the use of the same reagents for the detection of hydrogen ...
