Page/Page column 18, (2010/11/08)
A 4,5-dihydronaphtho[1,2-b]thiophene derivative expressed by the formula: (wherein R1 is a C1 to C10 1-hydroxyalkyl group or a C1 to C10 acyl group, and R2 and R3 separately substitute in the 6-, 7-, 8-, or 9-positions, and are each independently a hydrogen atom, a halogen atom, a C1 to C10 alkyl group, a hydroxy group, a C1 to C10 alkoxy group, a C1 to C5 alkenyloxy group, a C1 to C5 alkynyloxy group, a benzyloxy group, or the like, provided that when R1 is an acyl group and R2 is a hydrogen atom, then R3 is neither a hydrogen atom nor an acetyl group), or a pharmaceutically acceptable salt thereof. This is a novel compound that is effective in reducing triglyceride levels in the liver and reducing blood glucose levels.

A new access to 1-naphthylamines from the corresponding 3,4-dihydro-1(2H)-naphthalenones (α-tetralones) is described. It proceeds in a two-step sequence: preparation of the benzyl Schiff's base of an α-tetralone followed by aromatization over palladium ca

trans-6-Hydroxy-2-(1-methyl-3-phenylpropyl)amino-1,2,3,4-tetrahydronaphth alen-1-ol (8a), trans-6-hydroxy-2-(1-methyl-2-phenoxyethyl)amino-1,2,3,4-tetrahydronaphtha len-1-ol (8b) and trans-1,6-dihydroxy-2-(1-methyl-3-phenylpropyl)amino-1,2,3,4-tetrahydronap hthalene-5-carboxamide (9a) were synthesized as a part of our search for useful cardiovascular agents. 2-(N-Substituted amino)-6-alkoxy-1,2,3,4-tetrahydronaphthalen-1-ols (10-31) having various substituents at the 5-, 6- and 7-positions of the naphthalene ring were prepared by a five-step sequence of reactions starting from 3,4-dihydro-1(2H)-naphthalenone derivatives (36). Furthermore 2-(N-substituted amino)-1-indanol derivatives (33) and 6-(N-substituted amino)-2-hydroxy-6,7,8,9-tetrahydro-5H-benzocyclohepten-5-ols (34, 35) were obtained by the reductive alkylation of the corresponding amino alcohols with carbonyl compounds. These N-substituted amino alcohols (8-35) were tested for vasodilating activity in anesthetized dogs and for β-blocking activity using isolated guinea pig atrial preparations.
