合成路线1
该中间体在本合成路线中的序号:(IV)The cyclization of 4,4-diphenyl-2-cyclohexen-1-one (I) with N-benzyl-N-(butoxymethyl)-N-(trimethylsilylmethyl)amine (II) gives 2-benzyl-7,7-diphenylperhydroisoindol-4-one (III), which is debenzylated by hydrogenation with H2 over Pd/C to afford 7,7-diphenylperhydroisoindol-4-one (IV). The optical resolution of (IV) yields the desired enantiomer, which is finally condensed with 2-(2-methoxyphenyl)acetimidic acid ethyl ester tetrafluoroborate (V).
