Acronycine analogues of formula (I), their enantiomers, diastereoisomers, N-oxides, and addition salts with acids and bases are new. Either (a) X = -O-R'1, Y = -O-CO-R2 or (b) X = -O-CO-R1, Y = -O-CO-R2 or (c) X + Y = -O-CO-O- or (d) X +Y = -O-CO-A-CO-O-; R1, R2 = 1-6C hydrocarbon opt. substd. ≥ 1 OH, halo, nitro, amino, alkoxy, or acyl, R'1 = H or R1; A = bond or 1-6C bivalent hydrocarbon optionally carrying one or more unsaturations and opt. substd. by OH, halogen, nitro, amino, alkoxy or acyl, R3, R4, R6 = H or alkyl, R5 = H, OH, or alkoxy; alkyl, alkoxy, acyl groups have 1-6C and may be unsatd. and opt. substd. by OH, halo, nitro, amino, alkoxy or acyl. |
