rac-Diethyl 6-hydroxy-4-[(2-hydroxyethyl)amino]-6-methyl-2-phenylcyclohex-3-ene-1,3-dicarboxylate
The title compound, C(21)H(29)NO(6), is chiral with three stereogenic centres. The crystal is a racemate and consists of enanti-omeric pairs with the relative configuration rac-(2R*,3S*,4R*). The ethyl fragment of the eth-oxy-carbonyl group at position 1 is disordered in a 0.60:0.40 ratio. The crystal packing displays inter-molecular O-H⋯O hydrogen bonding. An intra-molecular N-H⋯O hydrogen bon...

The structure of the title compound, C(16)H(19)N(3)O(4)S, shows the planes described by the thio-phene and the pyrroles are twisted by 17.06 (4)°. Additionally, the structure shows the azomethine bond adopts the E configuration, while the pyrrole is disordered as a heterocycle flip [occupancy ratio 0.729 (5):0.271 (5)]. The three-dimensional network is well packed and involves N-H⋯O hydrogen bo...

Triphenyl phosphine(PPh3), an efficient and reusable catalyst, catalysed the synthesis of 2-amino-3-cyano-6-methyl-4-aryl-4H-pyran-5-ethylcarboxylate derivatives by one-pot condensation of aromatic aldehydes, malononitrile and ethyl acetoacetate in EtOH-H2O (1:1) at reflux conditions. The results show that ...

متن کاملDiethyl 2-{[(4-methoxy-3-pyridyl)amino]methylidene}malonate
In the title mol-ecule, C(14)H(8)N(2)O(5), the amino group is involved in the formation an intra-molecular N-H⋯O hydrogen bond. In the crystal, weak inter-molecular C-H⋯O and C-H⋯N hydrogen bonds link the mol-ecules into ribbons along the b axis.
