A Concise Route to a Key Intermediate in the Total Synthesis of Sempervirine1
摘要:
Diels-Alder reaction of 5-acetyl-3-methylthio-1,2,4-triazine 3 with 1-pyrrolidino-1-cyclohexene afforded 3-acetyl-1-methylthio-5,6,7,8-teterahydroisoquinoline 4 which was readily converted into target 2-(3-(5,6,7,8-tetrahydroisoquinolinyl)) 6 via Fisher synthesis followed by reductive cleavage of the methylthio group in 5.
