rac-2-[2-(4-Fluorophenyl)-2-oxo-1-phenylethyl]-4-methyl-3-oxo-N-phenylpentanamide
The title compound, C(26)H(24)FNO(3), is a critical inter-mediate of a selective and competitive inhibitor of the enzyme 3-hy-droxy-3-methyl-glutaryl-coenzyme A (HMG-CoA) reductase. Inter-molecular N-H⋯O hydrogen bonding generates a chain along [give direction] that is the dominant inter-action in the crystal packing. Inter-molecular C-H⋯O inter-actions are also observed.
متن کامل2-Bromo-2-methyl-N-(4-methyl-2-oxo-2H-chromen-7-yl)propanamide
In the title compound C(14)H(14)BrNO(3), the coumarin ring system is almost planar (r.m.s. deviation = 0.008 Å) and an intra-molecular C-H⋯O inter-action generates an S(6) ring. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, with the C=O unit of the coumarin ring system acting as the acceptor group, generating [010] C(8) chains. The chain connectivity is reinforced by two C-H⋯O ...
متن کاملDiethyl 2-oxo-3-(2-oxo-2,3-dihydro-1H-indol-3-ylidene)butanedioate
The title compound, C(16)H(15)NO(6), crystallizes with two symmetry-independent mol-ecules in the asymmetric unit. The crystal structure is stabilized by inter-molecular C-H⋯O and N-H⋯O hydrogen bonds, and intra-molecular C-H⋯O hydrogen bonds. In addition, the crystal structure exhibits two inter-molecular C-H⋯π inter-actions.

A novel nano-initiator containing kojic acid moiety, [5-(benzyloxy)-4-oxo-4H-pyran-2-yl)methyl-2-bromo-2-methylpropanoate was synthesized by the reaction of 5-(benzyloxy)-2-(hydroxymethyl)-4H-pyran-4-one with 2-bromoisobutyryl bromide in triethylamine and used as initiator in the atom transfer radical polymerization (ATRP) of styrene and methyl methacrylate in the presence of Cu(0)/CuCl2and N,N...
متن کامل2-(4-Isopropyl-4-methyl-5-oxo-4,5-dihydro-1H-imidazol-2-yl)-5-methylnicotinic acid
In the title herbicideh/phytocide, known as imaza-pic, C(14)H(17)N(3)O(3), the pyridine and imidazole rings are almost coplanar [dihedral angle = 3.08 (5)°]. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, an N-H⋯O hydrogen bond links mol-ecules into a chain parallel to [010].
