Chiral alcohols are ubiquitous in organic structures. One efficient method to generate chiral alcohols is the catalytic asymmetric addition of a carbon nucleophile to a carbonyl compound since this process produces a C-C bond and a chiral center simultaneously. In comparison with the carbon nucleophiles such as an organolithium or a Grignard reagent, an organozinc reagent possesses the advantag...

In the title compound, C(17)H(13)BrClNO, the dihedral angle between the naphthol ring system and the chloro-benzene ring is 76.59 (11)°. This twisted conformation is supported by an intra-molecular O-H⋯N hydrogen bond. In the crystal, [100] chains arise, with adjacent mol-ecules linked by an N-H⋯O hydrogen bond, a C-H⋯π inter-action and an aromatic π-π stacking contact [centroid-to-centroid sep...

In the title compound, C(23)H(25)NO, an intra-molecular O-H⋯N hydrogen bond defines the mol-ecular conformation; the naphthol mean plane and the benzene ring form a dihedral angle of 75.8 (2)°. The piperidine ring adopts a chair conformation. The crystal packing exhibits no short inter-molecular contacts.

The gold(I)-catalyzed intramolecular cycloisomerization of furan/ynes bearing a silyloxy or allyloxy group has been developed, which provides a highly efficient access to protected 1-naphthol derivatives with enal or enone moiety. The method offers several advantages such as high stereoselectivities, mild reaction conditions, and easily accessible starting materials. In addition, the naphthyl p...
