The asym. synthesis of 1,3-lactol-bridged tetrahydroisoquinolines I [R = SiMe2CMe3, CH2Ph; R1 = CH2CH(CO2Me)2; R2 = CO2CH2Ph] was developed. Subsequent cyclizations of I (R = SiMe2CMe3, CH2Ph) under acidic conditions lead to the formation of a tricyclic enamides II [R = SiMe2CMe3, CH2Ph; R1 = CH2CH(CO2Me)2; R2 = CO2CH2Ph]. II [R = CH2Ph, R1 = CH2CH(CO2Me)2, R2 = CO2CH2Ph] was in turn converted to a
非对称。合成 1,3-乳糖醇桥连的四氢异喹啉 I [R = SiMe2CMe3, CH2Ph; R1 = CH2CH(CO2Me)2;R2 = CO2CH2Ph] 被开发出来。I (R = SiMe2CMe3, CH2Ph) 在酸性条件下的后续环化导致形成三环烯酰胺 II [R = SiMe2CMe3, CH2Ph; R1 = CH2CH(CO2Me)2;R2 = CO2CH2Ph]。II [R = CH2Ph, R1 = CH2CH(CO2Me)2, R2 = CO2CH2Ph] 依次转化为四环化合物。三、[在 SciFinder (R) 上]
