Quinoline → HCID 15230863, compound

Participants

Reaction Steps

Rindler catalyst (90 mg) and quinoline (15 μl) were added to a solution of 7-(3,5,6-trimethyl-1,4-benzoquinon -2-yl)-7-phenyl-2-heptyn-1-ol (1.01 g, 3.0 mmole) in ethyl acetate (20 ml), and catalytic reduction was carried out at room temperature. 3 Hours later, when absorption (73 ml) of hydrogen was almost stopped, the reaction was suspended and the catalyst was filtered out. The ethyl acetate was distilled off under reduced pressure, and the residue was chromatographed on a silica gel column to elute with isopropayl ether to give (Z)-7-(3,5,6-trimethyl-1,4-benzoquinon-2-yl)-7-phenyl-2-hepten-1-ol (0.95 g, 94%). Its typical physical properties and nuclear magnetic resonance spectrum data are shown in Table 1.
