Synthesis of Podophyllotoxin and Related Analogues: Part III-Synthesis of &β-Apopicropodophyllin Analogues with Modified Lactone Ring

Four analogues (4-7) of β-apopicropodophyllin (2), a dehydration product of podophyllotoxin (1), have been synthesized starting from 2.The cyclic ether 4-(3',4',5'-trimethoxyphenyl)-6,7-methylenedioxy-1,3,4,9-tetrahydronaphthofuran (4) has been pre
