Stereoselective synthesis of (−)-irofulven has been achieved by cycloaddition of (R)-5-chloro-5-methyl-2-cyclopentenone to the 1,3-dipolar intermediate from 1-acetyl-1-(diazoacetyl)cyclopropane. The enantiomer, (+)-irofulven, was prepared in a similar way starting with (S)-5-chloro-5-methyl-2-cyclopentenone. (+)-Irofulven was 5 to 6 times less toxic than (−)-irofulven to adenocarcinoma (MV 522) cells
通过将(R)-5-氯-5-甲基-2-环戊烯酮环加成到1-乙酰基-1-(重氮乙酰基)环丙烷的1,3-偶极中间体中,已经实现了(-)-碘富勒烯的立体选择性合成。以(S)-5-氯-5-甲基-2-环戊烯酮为起始原料,以类似的方式制备对映体(+)-碘伏富烯。(+)-艾洛富尔文对腺癌(MV 522)细胞的毒性比(-)-艾洛富尔文低5至6倍。
