Kokai Tokkyo Koho JP 61204192 A2 10 Sep 1986 Showa, 7 pp. (Japan) CODEN: JKXXAF. CLASS: ICM: C07H015-26. ICS: C07H001-00. ICA: A61K031-70. APPLICATION: JP 85-43583 7 Mar 1985. DOCUMENT TYPE: Patent CA Section: 33 (Carbohydrates) Section cross-reference(s): 1 The title compds. (I; R1 = alkyl; R2, R3 = substituted benzyl), useful as antitumor agents (no data), were prepd. in improved yields by reductive dialkylation of I (R1 = alkyl, R2 = R3 = H) with aldehydes followed by isolation and reductive alkylation of the monoalkylated byproducts I (R1 = alkyl, R2 = substituted benzyl, R3 = H). Thus, a mixt. of 3,4-bis(benzyloxy)benzaldehyde and a Cu complex of I (R1 = Me, R2 = R3 = H).3HCl in MeOH contg. NaBH3CN at 40° for 35 h gave 25.6% a Cu complex of I [R1 = Me, R2 = 3,4-bis(benzyloxy)benzyl, R3 = H] and, after treatment with Amberlite XAD-2, 58.0% a free base I [R1 = Me, R2 = R3 = 3,4-bis(benzyloxy)benzyl] (II). The former compd. was converted into II by in an analogous manner in 68.4% yield which made the total yield of II 75.1%. .
