2-[2-(4-Methoxyphenyl)-2-oxoethyl]malononitrile

N′-{2-[2-(4-Methoxyphenyl)ethenyl]phenyl}acetamide

In the title compound, C(17)H(17)NO(2), the phenyl-ene rings are nearly coplanar [dihedral angle 7.3 (1)°]. The acetamido group is twisted out of the plane of the aromatic ring in order to form an N-H⋯O hydrogen bond to the acetamido group of an adjacent mol-ecule, generating a helical chain running along the b axis.

2-[2-(4-Methoxyphenyl)-2,3-dihydro-1H-1,5-benzodiazepin-4-yl]phenol

In the structure of title compound, C(22)H(20)O(2)N(2), the 11-membered benzodiazepine ring system adopts a distorted boat conformation. The benzene ring of this system forms dihedral angles of 89.69 (12) and 48.82 (12)° with those of the phenol and methoxy-phenyl substituents, respectively. The dihedral angle between the benzene rings is 49.61 (11)°. An intra-molecular O-H⋯N hydrogen bond gene...

Synthesis of 2-(4-methoxyphenyl)ethanol[ring-1-14C].

Methyl 3-(2-chlorophenyl)-2-(1H-indol-3-ylmethyl)-5-[1-(4-methoxyphenyl)-4-oxo-3-phenylazetidin-2-yl]-4-nitropyr­rolidine-2-carboxylate

In the mol-ecule of the title compound, C(37)H(33)ClN(4)O(6), the four-membered β-lactam ring is essentially planar and is oriented at dihedral angles of 30.0 (1), 76.3 (1) and 30.9 (1)° with respect to the methoxy-phenyl ring, the phenyl ring and the indole unit, respectively. The pyrrolidine ring adopts a twist conformation. Intra-molecular C-H⋯Cl and C-H⋯O hydrogen bonds result in the format...

Crystal structure of 3,3-dichloro-N-p-methoxyphenyl-4-(2-phenylstryl)-2-azetidinone.

3,3-Dichloro-N-p-methoxyphenyl-4-(2-phenylstryl)-2-azetidinone (C22H15Cl2NO2) was studied by X-Ray analysis, which indicated a monoclinic space group, P2(1)/c, with a = 9.619(5), b = 13.879(4), c = 14.161(5)A, beta = 100.16(3)degrees, V = 1860.8(13)A3, Z = 4, Dc = 1.414 g cm(-3), micro(Mo Kalpha) = 0.366 mm(-1) and F000 = 816. The structure was solved by direct methods and refined to R = 0.041 ...
