Participants

Reaction Steps

A total of 5.2 mL (10.4 mmol) of 2.0 M n-propylmagnesium bromide was added to a solution of 2.4 g (10 mmol) of ethyl 4-phenylbenzoylformate in THF in an analogous manner as described for the synthesis of 3,4-dihydroxy-5-methyl-5-phenyl-2(5H)-furanone to give prior to hydrogenolysis 0.30 g (8% yield) of 5-[(1,1′-biphenyl)-4-yl]-4-hydroxy-3-phenylmethoxy-5-propyl-2(5H)-furanone as an off white solid after crystallization from CHCl3 and hexanes.
