Three fungal metabolites with a common structural feature as prenylated phenols were synthesized in their naturally occurring and optically active forms: ascochlorin [(2',4',1',2',6')-(-)-5-chloro-2,4-dihydroxy-6-methyl-3-[5'-(1',2',6'-trimethyl-3'-oxo-cyclohexyl)-3'-methyl-2', 4'-pentadienyl] benzaldehyde], ascofuranone [(2',6',1')-(-)-5-chloro-2, 4-dihydroxy-6-methyl-3-[7'-(3',3'-dimethyl-4'-oxo
以天然存在的和光学活性的形式合成了具有作为戊烯基化酚的共同结构特征的三种真菌代谢物:抗坏血酸[(2' ,4' ,1' ,2' ,6' )-(-)-5-chloro-2 ,4-二羟基-6-甲基-3- [5'-(1',2',6'-三甲基-3'-氧代-环己基)-3'-甲基-2',4'-戊二烯基]苯甲醛] ,ascofuranone [(2' ,6' ,1' )-(-)-5-chloro-2,4-dihydroxy-6-methyl-3- [7'-(3',3'-dimethyl-4'-氧代-2'-氧杂环戊基)-3',7'-二甲基-2',6'-庚二烯基]苯甲醛]和糠醇[[2' ,6' ,1' ,4')-(-)-5-氯-2,4-二羟基-6-甲基-3- [7'-(3',3'-二甲基-4'-羟基-2'-氧杂环戊基)-3',7 '-二甲基-2',6'-庚二烯基]苯甲醛]。还合成了(+)-Asco呋喃酮和(+
