چکیده
The title compound, C(15)H(19)NO(4), contains one crystallographically independent mol-ecule in the asymmetric unit. The N-O-C-O torsion angle is 1.97 (9)°. The two pairs of vicinal H atoms that lie above or below the plane defined by the five-membered pyrrolidine-2,5-dione ring are an average of 6.57 (5)° from being eclipsed. The average absolute C-C-C-C torsion angle in the adamantane skeleton, in which each fused cyclo-hexane ring is in a chair configuration, is 59.99 (5)°. The crystal packing is unremarkable.

The title compound, C(11)H(9)NO(5), was prepared by the reaction of 2-furan-acrylic acid and N-hy-droxy-succinimide. The mol-ecule consists of two approximately planar moieties, viz. a succinimide group and the rest of the mol-ecule [the largest deviations from the least-squares planes are 0.120 (1) and 0.210 (1) Å, respectively]. The dihedral angle between these fragments is 63.70 (5)°. In the...

The asymmetric unit of the title compound, C(12)H(11)NO(5), contains two independent mol-ecules with similar geometric parameters but different orientations of the phenyl rings. The mol-ecular packing is stabilized by weak nonclassical C-H⋯O hydrogen-bonding inter-actions.

In the title compound, C8H9NO4, the pyrrolidine ring (r.m.s. deviation 0.014 Å) is almost normal to the mean plane of the propenoate group (r.m.s deviation 0.028 Å), making a dihedral angle of 86.58 (4)°. In the crystal, mol-ecules are linked via pairs of weak C-H⋯O hydrogen bonds, forming inversion dimers which stack along the c axis.

Development of multidrug resistance (MDR) to antimicrobial, antiparasitic and chemotherapeutic agents is a global challenge for the scientific community. Despite of the emergence of MDR pathogens, the development of novel and more effective drugs is slow and scientist even speculate that we are going back the pre-antibiotic era. This work aims to study and evaluate the preliminary antibacterial...

If Alexander Graham Bell were to come back to life and see what the telephone looks like today, compared with his own invention, he would definitely be astonished. It may not even be appropriate to call today’s devices “telephones.” They are multitasking gadgets capable of a myriad of other operations. It is astonishing that the Apple iPhone claims over 350 000 specialized applications (better ...
