合成路线1
该中间体在本合成路线中的序号：(XXV)The preparation of the hydroxylated adamantane (IV) is shown in Scheme 3. 1-Adamantyl bromide (XXII) is condensed with 1,1,2-tris(trimethylsilyloxy)ethylene (XXIII) by means of ZnCl2 in CH2Cl2 to afford the adamantylglycolic acid (XXIV), which is esterified to (XXV) utilizing a solution of acetyl chloride in MeOH. After Swern oxidation of (XXV) to the corresponding keto ester (XXVI), hydroxylation of the adamantane ring by means of HNO3/H2SO4 provides (XXVII). Alkaline hydrolysis of ester (XXVII) leads to the oxoacetic acid (XXVIII), which is converted to the target (S)-amino acid (IV) by reductive amination with phenylalanine dehydrogenase (3).
