(7-Dimethylamino-1-hydroxy-3-naphthyl)(morpholino)methanone

Coumarins and a naphthyl labdanoate diarabinoside from the fruits of Peucedanum grande C. B. Clarke.

Phytochemical investigations of the methanolic extract of the fruits of Peucedanum grande C. B. Clarke (Apiaceae) led to the identification of three coumarins and a naphthyl labdanoate diarabinoside characterized as 5-hydroxy-6-isopranyl coumarin (1), 5,6-furanocoumarin (2), 7-methoxy-5,6-furanocoumarin (3), and labdanyl-3alpha-ol-18-(3'"-methoxy-2"'-naphthyl-oate)-3alpha-L-arabinofuranosyl-(2'...

Proton sponge phosphines: electrospray-active ligands.

Attachment of a proton sponge to a phosphine ligand renders neutral complexes of the ligand highly amenable to analysis by electrospray ionisation mass spectrometry (ESI-MS). The ligand 1,8-bis(dimethylamino)naphthyldiphenylphosphine (3) is extremely efficient and highly selective in forming exclusively [M + H]+ ions, which may be detected at very low concentration. Ionisation efficiency of 3 i...

Screening Assessment for the Challenge Methanone, bis[4-(dimethylamino)phenyl]- (Michler’s ketone)

(4-Chlorophenyl)(2-hydroxy-7-methoxynaphthalen-1-yl)methanone

The title compound, C(18)H(13)ClO(3), has an intra-molecular O-H⋯O=C hydrogen bond between the carbonyl group and the hydr-oxy substituent on the naphthalene ring system. The angle between the C=O bond plane and the naphthalene ring system is relatively small [20.96 (8)°]. The angle between the benzene ring and the carbonyl group is rather large [35.65 (9)°] compared to that in an analogous com...
