合成路线1
该中间体在本合成路线中的序号：(XVIII)The intermediate (S)-adamantylglycine (I) can be prepared as follows. Reduction of adamantane-1-carboxylic acid (XVI) using LiAlH4 in THF gives the primary alcohol (XVII), which is oxidized to aldehyde (XVIII) under Swern conditions. Adamantane-1-carbaldehyde (XVIII) is then condensed with (R)-phenylglycinol (XIX) and KCN in the presence of NaHSO3 to yield the chiral aminonitrile (XX). After acidic hydrolysis of nitrile (XX) to the corresponding amino acid (XXI), the chiral auxiliary group is removed by hydrogenolysis over Pearlman’s catalyst to furnish intermediate (I) (1, 6). Scheme 2.
