Abstract: 9-(3,5-Dimethoxyphenyl)-5,8,8a,9-tetrahydrofuro (3',4':6,7)-naphtho(2,3-d)(1,3)-dioxol-6(5aH)-one derivatives (I) are new. Podophyllotoxin derivatives of formula (I) and their isomers and acid or base addition salts are new. R = -A-G or a bicyclic group of formula (a); X,Y = H, OH, alkoxy, NH2 or mono- or di-alkylamino; W = H, alkyl, aryl or heteroaryl; A = a direct bond or optionally unsaturated 1-6C alkylene (optionally substituted (os) by one or more of halo and OH); G = H, cycloalkyl, heterocycloalkyl, aryl, heteroaryl, OR2, -O-T1-NR3R4, -O-T1-NR2-T1'-NR3R4, NR3R4, -NR2-T1-NR3R4, -NR2-T1-OR5, -NR2-T1-COOR6, -NR2-T1-COR6, -CONR3R4, -CO-NR2-T2, -O-CO-NR2-T2, -O-CS-NR2-T2, -NR2-CO-T2, -NR2-CS-T2, -OCOOT2, -OCONR2-T2, -OC(S)OT2, -OC(S)NR2-T2, -NR2-COOT2, -NR2-CO-NR6-T2, -NR2-C(S)OT2, -NR2-CS-NR6-T2 or -NR2-SO2T3; R2 = H, alkyl, aryl or arylalkyl; T1, T1' = 1-6C alkylene; R3, R4 = H, alkyl (os by one or more OH), aryl, arylalkyl, cycloalkyl, heteroarylalkyl, heteroaryl, heterocycloalkyl or heterocycloalkylalkyl, or NR3R4 = 5-7 membered heterocyclyl, optionally containing a second O or N heterocyclyl and os by one or more of halo, OH, alkyl and heterocyclyl; R5 = alkyl, aryl or arylalkyl; T2 = H, alkyl (os by one or more halo), aryl, arylalkyl, cycloalkyl, cycloalkylalkyl, heterocycloalkyl or heterocycloalkylalkyl; or 1-6C alkylene substituted by one or more of NR3R4, OR2, COOR6, NR2COR6, NR2COOR6, COR6, CONR3R4, -NR2-T1-NR3R4, -NR2-T1-OR6 or -O-T1-NR3R4; T3 = 1-20C alkyl (os by one or more of halo, OR2, NR2R6, NO2, CN or N3), aryl, arylalkyl, cycloalkyl, cycloalkylakyl, heterocycloalkyl, heterocycloalkylalkyl, heteroaryl or heteroarylalkyl; R1 = H, alkyl, aryl, arylalkyl, heteroaryl, heteroarylalkyl, alkylcarbonyl, arylcarbonyl, arylalkylcarbonyl, heterocycloalkylcarbonyl, alkylsulfonyl, arylsulfonyl, arylalkylasulfonyl, phosphono, alkoxycarbonyl, aryloxycarbonyl or arylalkoxycarbonyl; aryl moieties = phenyl, biphenyl, naphthyl, di- or tetra-hydronaphthyl, indenyl or indanyl (all os by one or more of halo, OH, alkyl, alkoxy, CN, NO2, NH2, mono- or dialkylamino, alkylsulfonyl, alkylsulfonylamino, COOH, alkoxycarbonyl, aryloxycarbonyl, arylalkoxycarbonyl, hydroxyalkyl, trihaloalkyl, OCH2O, OCH2CH2O, morpholinyl, piperidyl, piperazinyl, alkylcarbonyloxy or alkylcarbonyl); heteroaryl moieties = 5-12 membered mono- or bi-cyclic aromatic system (where one ring of a bicyclic system is optionally partially hydrogenated), containing 1-3 of O, N and S as heteroatom(s) and os as for aryl; cycloalkyl moieties = 3-10C mono- or bi-cyclic saturated or unsaturated (but not aromatic) system (os by one or more of halo, alkyl, trihaloalkyl, OH, hydroxyalkyl, NH2, mono- or dialkylamino, piperidyl, piperazinyl and morpholinyl), and heterocycloalkyl moieties = as for cycloalkyl but containing 1 or 2 of O, N and S as heteroatom(s); provided that R1 is not Me if R is H; alkyl moieties have 1-6C unless specified otherwise. Independent claims are included for the following: (i) new intermediates (A), having formula as for (I) but with R replaced by N3, Cl, Br or -A1-CHO (A1 = 1-5C alkylene); and (ii) preparation of (I).
