The invention relates to indoles of general formula (I) ##STR1## wherein R.sub.0 represents a hydrogen atom or a C.sub.1-3 alkyl group; R.sub.1 represents a group R.sub.4 CONH--, R.sub.4 R.sub.5 NSO.sub.2 --, R.sub.4 SO.sub.2 NH-- or R.sub.4 R.sub.5 NCO-- (where R.sub.4 is a hydrogen atom or a C.sub.1-6 alkyl group, provided that R.sub.4 does not represent a hydrogen atom when R.sub.1 represents R.sub.4 SO.sub.2 NH--, and R.sub.5 is a hydrogen atom or a C.sub.1-6 alkyl, C.sub.3-7 cycloalkyl, phenyl or phen(C.sub.1-3)alkyl group in which the phenyl ring is optionally substituted by a halogen atom or a C.sub.1-4 alkoxy, hydroxy or C.sub.1-3 alkyl group); R.sub.2 is a hydrogen atom, a C.sub.1-3 alkyl, a C.sub.3-6 alkenyl, a phenyl or a phen(C.sub.1-3)alkyl group; R.sub.3 is a hydrogen atom, a C.sub.1-3 alkyl group or a group --CO.sub.2 R.sub.6, --COR.sub.6, --COCO.sub.2 R.sub.6 or --CONHR.sub. 6 where R.sub.6 is a hydrogen atom or a C.sub.1-4 alkyl, a C.sub.3-7 cycloalkyl, a C.sub.3-6 alkenyl, an aryl or an ar(C.sub.1-4)alkyl group in which the aryl group may be unsubstituted or substituted by a halogen atom or a C.sub.1-4 alkoxy, C.sub.1-4 alkyl or hydroxy group, provided that when R.sub.3 is --CO.sub.2 R.sub.6, R.sub.6 is other than hydrogen; n is zero or an integer from 1 to 5; and pharmaceutically acceptable salts thereof.

pyridoazepines, designed as simplified analogues of the alkaloid galanthamine, were synthesised and evaluated as inhibitors of acetylcholinesterase. The key cyclisation step involved internal displacement of 2-chloro or 2-iodopyridine by either nucleophilic aromatic substitution or a Heck reaction. The target compounds showed significant inhibition of acetylcholinesterase but lower than that of galanthamine

The present invention is directed to a method for the synthesis of a bi-functional complex comprising a molecule part and an identifier oligonucleotide part identifying the molecule part. A part of the synthesis method according to the present invention is preferably conducted in one or more organic solvents when a nascent bi-functional complex comprising an optionally protected tag or oligonucleotide identifier is linked to a solid support, and another part of the synthesis method is preferably conducted under conditions suitable for enzymatic addition of an oligonucleotide tag to a nascent bi-functional complex in solution.
