R. Pech et R. Bohm, ON THIENO-COMPOUNDS .15. REACTION OF 2-AMINOTHIOPHENES WITH BISMETHYLTHIOMETHYLENE DERIVATIVES, Die Pharmazie, 48(4), 1993, pp. 257-259
By reaction of 2-aminothiophenes with bismethyl-thiomethylene compound
s some new thiophene derivatives are synthezised appropriate for cycli
zation to obtain thieno-condensed heterocycles. Bismethylthiomethylene
malonic acid derivatives. N-(bismethylthiomethylene)cyanamid and the
ethylic ester of N-(bismethylthiomethylene)aminoacetic acid are used a
s ambifunctional agents. Resulting from the different electrophilic pr
operties the exchanged of a methylthio group or a reaction with an oth
er functional residue can be observed.
