Reactions of 5-Aroylmethylene-3-benzyl-4-oxo-2-thioxo-1,3- thiazolidines with Nitrile Oxides
E,Z-5-Aroylmethylene-3-benzyl-4-oxo-2-thioxo-1,3-thiazolidines (3a-c) react with 4-methoxy and 4-chlorophenylnitrile oxides (4a and b) in pyridine solution to afford one or more of the following compounds: Z-3, Z-2,4-dioxo analogues 5 and 3,6-diaryl1,4,2,5-dioxadiazines (6a-b). The interconversion route is discussed and the structures of all of the synthesised compounds are proven by microanaly...
متن کامل(4S)-4-Benzyl-N-{[(4S)-4-benzyl-2-oxo-1,3-oxazolidin-3-yl]sulfonyl}-2-oxo-1,3-oxazolidine-3-carboxamide
The title compound, C(21)H(21)N(3)O(7)S, contains an oxazolidinone ring and a sulfonamide group, both characteristic for biologically and pharrmaceutically active compounds. Both stereogenic centres reveal an S absolute configuration. The two oxazolidinone rings are in an envelope conformation with the methyl-ene carbon flap atoms deviating by 0.428 (1) and 0.364 (2) Å from the best least-squar...
متن کاملMethyl 2-benzyl-5-[1-(4-methoxyphenyl)-4-oxo-3-phenylazetidin-2-yl]-4-nitro-3-phenylpyrrolidine-2-carboxylate
In the title mol-ecule, C(35)H(33)N(3)O(6), the pyrrolidine ring adopts a twist conformation. The mol-ecules are paired into centrosymmetric dimers by weak inter-molecular C-H⋯O hydrogen bonds. The dimers inter-act further again via C-H⋯O hydrogen bonds and N-H⋯O intramolecular interaction also stabilize the crystal packing.
متن کامل(4S)-Benzyl 4-isopropyl-5-oxo-1,3-oxazolidine-3-carboxylate
In the crystal structure of the title compound, C(14)H(17)NO(4), obtained by the reaction of N-benzoxycarbonyl-l-valine, paraformaldehyde and 4-methyl-benzene-sulfonic acid, mol-ecules are linked by C-H⋯O hydrogen bonds, generating linear chains parallel to the a axis. C-H⋯π inter-actions of stacked benzene rings also provide stability for the crystal structure.
متن کامل(4-Benzyl-2-oxo-1,3-oxazolidin-5-yl)methyl methanesulfonate
The title compound, C(12)H(15)NO(5)S, features an approximately planar five-membered oxazolidin ring (r.m.s. deviation = 0.045 Å) with the peripheral benzyl and methyl methane-sulfonate residues lying to either side of the plane. In the crystal, N-H⋯O hydrogen bonds, involving one of the sulfur-bound oxo groups as acceptor, lead to the formation of supra-molecular chains along the b axis. These...
