provides conditions suitable for the use of less stable aldehydes and amines in this Chichibabin pyridine condensation. The evaluation of selected 1,3,5-trisubstituted pyridinium salts highlighted that they can inhibit the growth of S. aureus in the low μg/mL range. The synthetic accessibility of these compounds and preliminary growth inhibition data may pave the way towards the discovery of new anti-bacterials

A 1,3,5-trisubstituted pyridinium salt of general formula I (I) wherein Xn- is a counterion in which n is an integer from 1 to 4; wherein R2 and R3 are each independently a substituent group comprising Ar, wherein Ar is an aryl or heteroaryl group, which is substituted or unsubstituted; wherein R1 is a substituent group linked to the quarternary nitrogen of the pyridinium ring by an aliphatic carbon; and wherein, when R1 is benzyl, R2 and R3 are not both phenyl, 3-MeO phenyl, 4-Br phenyl, 3-CF3 phenyl, 2-Me phenyl or 4-(4-tert BuPh) phenyl; when R1 is 3-MeO phenethyl, R2 and R3 are not both 3-MeO phenyl; and when R1 is dimethoxyphenethyl, R2 and R3 are not both phenyl.
