Pd‐Catalyzed Asymmetric Dearomative Heck/Tsuji‐Trost Difunctionalization of Naphthalenes
Advanced Science, EarlyView.We have developed a palladium‐catalyzed asymmetric dearomative Heck/Tsuji‐Trost 1,4‐difunctionalization reaction of naphthalenes, affording 4‐aminospirocyclohexene oxindole products bearing two remote chiral centers. Through the effect of the newly designed chiral sulfinamide phosphine ligand with large steric hindrance, side reactions are inhibited ...

OBSERVATIONS ON NAPHTHOL STAINING AND THE HISTOCHEMICAL LOCALIZATION OF ENZYMES BY NAPHTHOL-AZO DYE TECHNIQUE [PDF]
, 1957 A group of naphthols—1- and 2-naphthol, 6-benzoyl-2-naphthol and 6-bromo-2-naphthol—have been investigated in relation to their tissue affinity. It has been found that naphthol binding is mainly dependent on the solubility of the naphthols and on the ...
