New triazolo-thieno-1,4-di:azepine derivs

Thienodiazepines of formula (I), as racemates, enantiomers, etc. and their acid addn. salts are new: R1 = H, 1-4C alkyl (opt. substd.), 3-5C cycloalkyl, 1-4C alkoxy or halo; R2 = -G-Ra; when n is not zero, Rn = H, halo, OH, NR6R7, arylsulphonyloxy (opt. substd.), alkylsulphonyloxy, arylcarbonyloxy (opt. substd. ), 1-12C alkylcarbonyloxy (opt. interrupted by N, O or S), R8NH.COO, etc. G = alkyl, alkenyl or alkynyl with a n carbon atoms, opt. substd. by aryl or another Ra; n = 0-10, but must be greater than zero when G = alkenyl or alkynyl; R6 and R7 = H; opt. substd. phenyl; 1-10C alkyl, alkenyl or alkynyl (opt. substd. by halo, OH, opt. substd. phenyl or C-bound heterocycle, and the C chain can be interrupted by N, NH, O or S). etc. R8 = 1-4C alkyl, alkenyl or alkynyl (opt. halo substd.) or aryl (opt. substd. by 1 or more 1-4C alkyl and/or alkoxy); R3 = H, opt. substd. phenyl or 1-4C alkyl, or R2 + R3 are together a gp. of formula (i). A = fused, mono-unsatd. 5-7 membered ring. I = alkyl, alkenyl or alkynyl with m C atoms; m = 0-6; R6 = H, OH, NH2, CHO, COOH, CN, 1-18C alkoxycarbonyl (opt. substd. by OH, NH2, NO2 or halo), etc. R4 is not phenyl (opt. substd. by halo, Me, CF3 or NO2), pyridyl or thienyl; X and Y are each CR1 or N (but not both CR1) or Y = C-COOR' and X = N; R1 = H or alkyl. Also new are intermediates in prepn. of (I).
