A Practical Synthesis of the Anti-tumour Agent 2-Methyl-4-deoxyisopicropodophyllotoxin and Related Podophyllin Analogues

We describe an efficient, six-stage synthesis of 2-methyl-4-deoxyisopicropodophyllotoxin, which proceeds via a Diels-Alder cycloaddition between 2-methylmaleic anhydride and the orthoquinodimethane generated by treatment of 5-1-acetoxy-1-(3',4',5'-trimet

A FACILE SYNTHESIS OF THE SUBSTITUTED TETRAHYDRONAPHTHALENES BY THE BENZO-PETERSON REACTION

Thermal treatment of the o-hydroxymethylbenzylsilanes with an excess maleic anhydride or 2,3-dichloromaleic anhydride afforded the corresponding substituted tetrahydronaphthalenes stereoselectively in satisfactory yields presumably via the o-quinodimethane intermediates generated by the benzo-Peterson reaction.
