Total Synthesis of (±)-Deethyleburnamonine and Vindeburnol (RU 24722) with the Corresponding Nitriles as Starting Material
摘要:
Cyclisation occurred during base treatment of cis-nitrile (5). The resulting new imine (6) was converted into the therapeutically important deethyleburnamonine (4). Total synthesis of vindeburnol (RU 24722) (3), another important drug, was achieved in one step starting from the trans-nitrile (9).
A concise stereoselectivetotalsynthesis of (±)-vindeburnol and its epimer (±)-16-epi-vindeburnol is presented. This synthetic work features the utilization of Baeyer–Villiger oxidation to install different types of lactone substrate, and a sequence of aminolysis, aldimine condensation and acyl-Pictet–Spengler to deliver the crucial trans-fused indoloquinolizidine scaffold with high-level diastereocontrol
