agents active against alcohol self-administration, a two-step route was developed. This process involves a palladium-catalyzed Buchwald–Hartwig coupling and an intramolecular Heck reaction. This two-step route provides rapid access to multigram quantities of 3-PBC (1) and βCCt (2), as well as analogues for studies of alcohol self-administration. The overall yield of 3-PBC (1) was improved from 8% to 50%
为了获得 3-丙氧基-β-咔啉盐酸盐 (3-PBC·HCl) ( 1·HCl ) 和 β-咔啉-3-
羧酸-叔丁酯 (βCCt) ( 2 ),这些潜在的抗
酒精临床药物自我管理,制定了一个两步路线。该过程涉及
钯催化的 Buchwald-Hartwig 偶联和分子内 Heck 反应。这种两步法可以快速获得数克数量的 3-PBC ( 1 ) 和 βCCt ( 2 ),以及用于
酒精自我管理研究的类似物。通过这条路线,3-PBC( 1 )的总产率从8%提高到50%。
