PROCEDURE
实验过程
In a process analogous to Step 6 METHOD A, using alternative Ru(II)-chiral diphosphine complexes in place of RuCl2(DMF)n[(R)—Cl—MeO-BIPHEP)] as the hydrogenation catalyst, one can obtain the identical products with varying enantiomeric excess at C-5. For example, in the reduction of 7-[2-(4-fluorophenyl)-5-isopropyl-3-phenyl-4-phenylcarbamoyl-pyrrol-1-yl]-3,5-dioxo-heptanoic acid, ethyl ester to (5R)-7-[2-(4-fluorophenyl)-5-isopropyl-3-phenyl-4-phenylcarbamoyl-pyrrol-1-yl]-3,5-dihydroxy-heptanoic acid, methyl ester proceeded as follows:
