The title compound, C 18 H 20 ClNO 2 , has been synthesized by the reaction of 4-chlorobenzaldehyde, Meldrum's acid, dimedone and CH 3 NH 3 Cl(NaOAc) in ethanol under microwave irradiation. The pyridone ring adopts a screw-boat conformation and the cyclohexenone ring an envelope conformation.
The title compound, C 30 H 52 O 2 , crystallizes with two molecules in the asymmetric unit. The independent molecules differ in the conformation of the side chain attached to C17. Hydrogen bonds link the molecules in an in®nite chain, graph-set C(8), parallel to the b axis.
The molecule of the title compound, C 18 H 15 NO 2 , is not completely planar. It adopts a keto±amine tautomeric form with an intramolecular NÐHÁ Á ÁO and an intermolecular OÐ HÁ Á ÁO hydrogen bond. The molecules are linked by OÐ HÁ Á ÁO hydrogen bonds into a three-dimensional network.
The title compound, C 18 H 26 ClNO 2 , is one of a group of decahydroisoquinoline derivatives that are known to exhibit a diverse range of bioactivities. The piperidine and cyclohexanone rings exist in chair conformations and form a cisfused decalin-type bicyclic framework. In the crystal structure,
The title compound, C 25 H 26 O 2 , was isolated and characterized as a stable intermediate in the conversion of 2,2-diphenylethyl 2,4,6-trimethylphenyl ketone to its formaldehyde-derived enone.
