Abstract:
A compound of the general formula in whichR1 and R2 can be the same or different and represent hydrogen, oxygen, halogen, hydroxy, thio or substituted thio, amino or substituted amino, carboxy, lower alkyl, lower alkenyl, lower alkinyl, aryl, lower alkyloxy, aryloxy, aralkyl, aralkyloxy or a reporter group, R3 and R4 each represent hydrogen, hydroxy, thio or substituted thio, amino or substituted amino, lower alkyloxy, lower alkenoxy, lower alkinoxy, a protecting group or a reporter group, R5 represents hydrogen, hydroxy, thio or substituted thio, amino or a substituted amino group, a reactive trivalent or pentavalent phosphorus group such as e.g. a phosphoramidite or H-phosphonate group, an ester or amide residue that can be cleaved in a suitable manner or a reporter group, R4 and R5 together form a further bond between C-2â€² and C-3â€² or an acetal group, R6 represents hydrogen or a hydroxy, thio or substituted thio, amino or substituted amino group, R7 represents hydrogen, a monophosphate, diphosphate or triphosphate group or the alpha, beta or gamma thiophosphate analogue of this phosphoric acid ester or a protective group as well as possible tautomers and salts thereof, X denotes methylene or methine substituted with halogen, hydroxy, thio or substituted thio, amino or substituted amino, carboxy, lower alkyl, lower alkenyl, lower alkinyl, aryl, lower alkyloxy, aryloxy, aralkyl, aralkyloxy or a reporter group, or oxygen and n=0 or 1, Z denotes nitrogen or carbon provided that if Z denotes nitrogen, m is zero (0) and if X represents methylene, substituted methylene or substituted methine, Z cannot be carbon and if X denotes oxygen, Z cannot be nitrogen and if Z denotes carbon, R2 cannot be hydrogen.
