Design, synthesis and antimicrobial properties of novel 3,3a,4,5,6,7- hexahydroindazole and arylthiazolylpyrazoline derivatives.

A remarkable diastereoselective synthesis of some novel arylthiazolyl pyrazoline derivatives 3(a-l) is displayed which were evaluated for their in vitro antimicrobial activities. In particular, compounds 3e, 3g & 3l (MIC 12.5 μg /ml) showed good activity against S.
