Cyclobuta-indole derivatives (I), their isomers and salts are new. The new compounds are of formula (I): n = 0 - 6; R1 = H, OH, CN, alkoxy, alkoxycarbonyl, carboxy, amino carbonyl (optionally substituted by one or two alkyl, aryl, or aralkyl groups), or NR4R5; R2 = H, alkyl, CH2OH, a croup -(OH)(T), or -U'-V'-W'; T = 3-12C mono- or polycyclic cycloalkyl that may have one C atom replaced by O, Se, S, SO, SO2, or SiR6R7; R3 = H, alkyl, aryl, or heteroaryl; R4 and R5 = alkyl, aryl, aralkyl, heteroaryl, heteroaryl alkyl, cycloalkyl, cycloalkyl alkyl, alkenyl or alkynyl; R6 and R7 = alkyl; U' = methylene or a bond; V' = a bond, O, S, SO, or SO2; and W' = aryl aralkyl, cycloalkyl, or cycloalkyl alkyl. All alkyl, alkoxy, alkenyl and alkynyl groups having up to 6 C atoms, aryl, heteroaryl and cycloalkyl groups may be mono or polycyclic, aryl and heteroaryl groups may be mono or polysubstituted and cycloalkyl groups may contain unsaturation. |
