pronounced antiinflammatory activity in the carrageenan-induced edema test in the rat. The activity was limited mainly to derivatives of p-haloacetophenone oxime and of p-halobenzaldehyde oxime. Nevertheless, the hydroxyethyl and carboxyalkyl groups may be converted into many derivatives with maintenance of activity. Some structure-activity relationships are in contrast to those of the well-known antiinflammatory
The first enantioselective Friedel-Crafts alkylation-acetalization-cascade of naphthols with alpha,beta-unsaturated cyclic ketones and 1H-inden-1-ones was realized. 9-Amino(9-deoxy)epi-quinine A was the catalyst of choice for the realization of polycyclic structures with high enantiocontrol.

We report the synthesis of orthogonally functionalized naphthalenes from simple, commercially available indanones in four steps. The developed method proceeds through a two‐step process that features a thermallyinduced fragmentation of a cyclopropane indanone with simultaneous 1,2‐chloride shift. Migration of the chloride substituent occurs in a regioselective manner to preferentially afford the para‐chloronaphthol
