A is S(O)m, -CH=CH-, O or NH;
R¹ is hydrogen, optionally substituted alkyl, halogen or R²⁰S(O)q;
R² and R³ are hydrogen, alkyl, alkenyl or alkynyl, each of which is optionally substituted, aryl, heterocyclyl, cyano, halogen, nitro, YR²⁰, S(O)₂NR⁸R⁹, CHO and functional derivatives thereof, NR⁸R⁹ or CYNR⁸R⁹;
either (i) R⁴ and R⁷ which may be the same or different, are hydrogen, optionally substituted alkyl, optionally substituted alkenyl, acyl or optionally substituted alkoxycarbonyl, and R⁶ is hydrogen, or
(ii) R⁴ is as defined above and R⁶ and R⁷ form a bond or R⁷ is as defined above and R⁴ and R⁶ form a bond;
R⁵ is hydrogen, alkyl, optionally substituted amino or halogen;
R⁸ and R⁹ are the same or different and are hydrogen, optionally substituted alkyl, acyl or aryl, or together with the nitrogen to which they are attached, form a 5 to 7 membered ring which can contain other hetero atoms;
