4- pyrazolines

Pyrazolines are a class of heterocyclic molecules comprised of two N and three C atoms arranged in the sequence -N-N=C-C-C-. 

Hole mobilities of a series of pyrazoline, oxadiazole, and stilbene doped PC were described by Sugiuchi et al. (1991). The donor compounds were selected for differences in dipole moment and varied from 1.42 to 5.56 Debye. The results are shown in Fig. 96. The mobilities decrease with increasing dipole 

The difference in the temperature dependence in the nondispersive and dispersive regimes is due only to the difference in the constant in the exponent (in the nondispersive regime, the constant is 2/3). A further prediction of the simulations is that Tc is related to a as 

Reaction of substituted hydrazine analogue with protected 3-dicarbonyl compound 67 leads to a ring-forming two-site reaction and formation of the pyrazoline diuretic agent, muzolimine (68).  

As a bioisoteric replacement for a substituted pyrrole ring, a pyrazole ring is a key feature of the nonsteroidal 

The 2-aminooxazole analogue, isamoxole (74), is an anti asthmatic agent. Its synthesis follows the classic pattern of condensation of hydroxy acetone with ji-propylcyanamide to establish the heterocyclic ring (21) The synthesis of isamoxole (74)
