The synthesis of 20 arylidenecamphors and 15 pyrimidines with camphane skeleton is described in the current report. A modified method for preparation of sterically hindered 2-aminopyrimidines in two steps was demonstrated. The evaluation of their in vitro activity against Mycobacterium tuberculosis H37Rv showed different MIC values (up to 0.91 μM for ketone 39). Compound 35 demonstrated moderate (8.23 μM), but ...
