The first phosphoric acid catalyzed direct arylation of 2-naphthylamines with iminoquinones for the atroposelective synthesis of axially chiral biaryl amino alcohols has been developed. This reaction constitutes a highly functional-group-tolerant route for the rapid construction of enantioenriched axially chiral biaryl amino alcohols, and is a rare example of 2-naphthylamines acting as nucleophiles in an organocatalytic enantioselective transformation. Furthermore, the products, which feature various halogen atoms, provide access to structurally diverse axially chiral amino alcohols through further transformations.
Fluorine-substituted derivatives of the carcinogenic dihydrodiol and diol epoxide metabolites of 7-methyl-, 12-methyl- and 7,12-dimethylbenz[a]anthracene

Stereospecific syntheses of the trans-3,4-dihydrodiol metabolites of 9- and 10-fluoro-7, 12-dimethylbenz[alanthracene, -7-methylbenz[a]anthracene, and -12-methylbenz[a]anthracene are described. These dihydrodiols are putative proximate carcinogenic metabolites that undergo activation by the P-450 microsomal enzymes to ultimate carcinogenic anti- and syn-diol epoxide metabolites that bind to nucleic acids in vivo. Syntheses of several of the anti- diol epoxide metabolites are also described.

A convenient preparative route has been developed for the synthesis of hexahydropyrroloisoquinolines involving condensation of an araldehyde with ethyl 4-nitrobutanoate followed by LAH reduction and subsequent cyclization with H2SO4 to 2-arylmethylpyrrolidines.The latter on formylation and Bischler-Napieralsky cyclization followed by NaBH4 reduction give the required pyrroloisoquinolines.Using this method, 8-methoxy-1,2,3,5,10,10a-hexahydropyrroloisoquinoline (IXa); 7,8-dimethoxy-1,2,3,5,10,10a-hexahydropyrroloisoquinoline (IXb); 7,9,10,11,11a,12-hexahydrobenzopyrroloisoquinoline (Xa); 3-methoxy-7,9,10,11,11a,12-hexahydrobenzopyrroloisoquinoline (Xb); 7,7a,8,9,10,12-hexahydrobenzopyrroloisoquinoline (XIa); 3-methoxy-7,7a,8,9,10,12-hexahydrobenzopyrroloisoquinoline (XIb) and 2,3-dimethoxy-7,7a,8,9,10,12-hexahydrobenzopyrroloisoquinoline (XIc) have been synthesized.None of these compounds has shown any noteworthy anticancer activity while few have exhibited interesting antihistaminic, β-blocking, hypertensive, antiinflammatory and antireserpine activities.
