A convenient route for the synthesis of (S)-1-amino-2-(1-methoxy-1-methylethyl)pyrrolidine (SADP) was
established. The route involved three key steps viz. the Grignard addition to the N-Boc-proline ester (1), nitrosation to the
aminoalcohol hydrochloride (3) and O-methylation to the alcohol group of N-nitrosopyrrolidine (4). (S)-1,1-dimethyl–
tetrahydropyrrolo[1,2-c]oxazol-3-one (6) was also obtained via the reaction of (S)-1-Boc-2-(1-hydroxy-1-
methylethyl)pyrrolidine (2) with sodium hydride.
建立了一条合成(S)-1-氨基-2-(1-甲氧基-1-甲基乙基)吡咯烷(SADP)的简便路线。该路线涉及三个关键步骤,即 N-叔丁氧羰基脯氨酸酯的格氏加成(1)、氨基醇盐酸盐的亚硝基化(3)和 N-亚硝基吡咯烷醇基的 O-甲基化(4)。(S)-1-叔丁氧羰基-2-(1-羟基-1-甲基乙基)吡咯烷(2)与氢化钠反应也得到了(S)-1,1-二甲基-四氢吡咯并[1,2-c]恶唑-3-酮(6)。
