Acetone Cyanohydrin → HCID 14793311, compound

Participants

Reaction Steps

To a mixture of 1-(4-chloro-2-nitrobenzoyloxy)-4a,5,6,7, 8,8a-hexahydro-3(4H)-naphthalenone and 3-(4-chloro-2-nitrobenzoyloxy)-4a,5,6,7,8,8a-hexahydro-l(4H)-naphthalenone (17.75 g, 50.6 mmol) in 100 ml of acetonitrile is added triethylamine (14.1 ml). Acetone cyanohydrin (2.5 ml) is added and the mixture is stirred overnight at RT. The solvent is removed under vacuum and the residue is dissolved in ether. The solution is washed with 2N HCl, separated and the organic layer is dried. The crude product is purified by chromatography to give 2-(4-chloro-2-nitrobenzoyl)-4a,5,6,7, 8,8a-hexahydro-1,3-(2H,4H)-naphthalenedione, a pure white crystalline solid (compound 1), m.p. 112°.
