中文摘要:
五 glutarimide 碱 cordiarimide A (5 ) , cordiarimide B (6 ) , crotonimide A (3 ) , crotonimide B (4 ) ,和 julocrotine (2 ) 被综合了从 Boc-L-glutamine (7 ) 开始。cordiarimides B (6 ) 的 benzylic 白酒 chiral 中心被催化不对称的加氢用周的催化系统 Pd (CF3CO2 )2/ 在 6:1 diastereoselectivity 建立了(R, R )-Me-DuPhos。
英文摘要:
Five glutarimide alkaloids cordiarimide A (5), cordiarimide B (6), crotonimide A (3), crotonimide B (4), and julocrotine (2) have been synthesized starting from Boc-L-glutamine (7). The benzylic alcohol chiral centre of cordiarimides B (6) has been established in 6 : 1 diastereoselectivity by catalytic asymmetric hydrogenation using Zhou's catalytic system Pd(CF3CO2)2/(R,R)-Me-DuPhos.
