tert-Butyl 2-[4-(2-{4-[(tert-butoxycarbonyl)methoxy]-3-methylphenyl}-2-propyl)-2-methylphenoxy]acetate
In the mol-ecule of the title compound, C(29)H(40)O(6), the carbon atom belonging to the propyl chain is connected to two aromatic rings that open up the C(ar-yl)-C-C(ar-yl) angle to 111.5 (1)°. The four-atom -O-CH(2)-C(=O)-O- linkage between the aromatic ring and the tert-butyl group assumes a (-)anti-periplanar conformation for one substituent and a (-)syn-periplanar conformation for the othe...

Straightforward conversion of (+)-6,8-dimethoxy-3,4-dihydro-3- undecylisocoumarin (3) to the title isocoumarin was carried out. Hydrolytic ring opening of (3) afforded the hydroxy acid (4) which was immediately oxidized to keto acid (5) using chromic acid, Cyclodehydration of (5) afforded the 6,8- dimethoxy-3-undecylisocoumarin (6) which on selective demethylation of 8- methoxy group furni...

In the title compound, C(15)H(16)F(3)NO(2), the dihedral angle between the benzene ring and the conjugated part of the cyclo-hexene ring is 60.00 (8)°. The non-conjugated part of the cyclohexene ring and the trifluoro-methyl group are both disordered over two sets of sites with occupancies of 0.835 (2) and 0.165 (2). In the crystal, mol-ecules are linked into chains along [010] by inter-molecul...
متن کامل1-(2,4-Dichlorophenyl)-3-[4-(dimethylamino)phenyl]prop-2-enone
In the title compound, C(17)H(15)Cl(2)NO, the dimethyl-amino-phenyl group is close to coplanar with the central propenone group [dihedral angle = 13.1 (1)° between the mean planes], while the dichloro-phenyl group is twisted from the plane [dihedral angle = 64.0 (1)°]. In the crystal, C-H⋯O and weak C-H⋯π inter-actions are formed between mol-ecules.
