TCI Practical Example: Introduction of Cyano Group with Homologation Using TosMIC
-
Used Chemicals
-
- p-Toluenesulfonylmethyl Isocyanide (=TosMIC) [T1046]
- 2-Adamantanone [A0719]
- Potassium tert-Butoxide (= tBuOK) [P1008]
- 2,2-Dimethoxyethane (= DME)
- Ethanol (= EtOH)
-
Procedure
-
tBuOK (934 mg, 8.32 mmol, 2.5 eq.) was added to a solution of 2-adamantanone (500 mg, 3.33 mmol) and TosMIC (845 mg, 4.33 mmol, 1.3 eq.) in DME/EtOH (10.4 mL/0.8 mL), cooling with a water bath and the mixture was stirred for 30 minutes at room temperature. And then the reaction mixture was stirred for 4 hours at 40 °C. The reaction mixture was filtered and the insoluble was washed with DME. The filtrate was concentrated under reduced pressure to a volume of 2-3 mL, and the residue was charged with neutral alumina (10 g), eluted with a mixture of hexane:dichloromethane = 5:1 (60 mL) and concentrated under reduce pressure to give 2-cyanoadamantane as a white solid (441 mg, 82% yield).

Experimenter’s Comments
-
The reaction mixture was monitored by TLC (ethyl acetate:hexane = 1:10, Rf = 0.6).

Synthesis of Heterocyclic Compounds using TosMIC (Multicomponent Reactions)
Typical Procedure (Entry 3):
To a stirred solution of o-phenylenediamine (1.0 mmol) in toluene (20 mL), 4-chlorobenzaldehyde (1.0 mmol) is added and stirring is continued for 5 min. Then TosMIC (1.0 mmol) and DABCO (1.2 mmol) are added and the reaction mixture is heated to 80 °C for 4 h. The resulting solution is initially washed with 5% HCl, then with H2O and dried. The solvent is distilled off under reduced pressure to yield the corresponding crude product mixture, which is purified by silica gel chromatography (petroleum ether : EtOAc = 10 : 1) as eluent, to give the desired quinoxaline derivative in 84% yield as yellow crystals.
