rac-Ethyl 2-hydroxy-2,7,7-trimethyl-4-(4-nitrophenyl)-5-oxo-3,4,5,6,7,8-hexahydro-2H-chromene-3-carboxylate

The title molecule, C(21)H(25)NO(7), has four stereogenic centres and crystallized as a racemate. It consists of enantiomeric pairs with the relative configuration rac-(1R*,2S*,3R*). The cyclohexenone ring adopts an envelope conformation; the dimethyl-substituted C atom lies 0.640 (1) Å out of th...
