Several pinacol derivatives of podophyllotoxins bearing different side chains and functions at C-7 were synthesized through reductive cross-coupling of podophyllotoxone and several aldehydes and ketones. While possessing a hydroxylated chain at C-7, the compounds retained their respective hydroxyl group with either the 7α (podo) or 7β (epipodo) configuration. Along with pinacols, some C-7 alkylidene
