5 S ,6 R ,9 RS )-9-Ethyl-3,4,5-trihydroxy-1,7-dioxaspiro[5.5]undecane ( 9 ) has been synthesised from 2,3:4,5-di- O -isopropylidene-β- d -fructopyranose ( 3 ) and transformed into (−)-talaromycin A ( 1 ). (−)-Talaromycin B ( 2 ) was obtained by isomerisation of 1 in acid medium.
摘要从2,3合成了(3 R,4 R,5 S,6 R,9 RS)-9-乙基-3,4,5-三羟基-1,7-二氧杂螺[5.5]十一烷(9): 4,5-二-O-异亚丙基-β-d-果糖吡喃糖(3)并转化为(-)-talaromycin A(1)。(-)-Talaromycin B(2)是通过在酸性介质中将1异构化而获得的。
