REGIOSELECTIVITY OF REDUCTION OF 2-tert-BUTYL-1-BENZOPYRILIUM PERCHLORATE

The reaction of 2-tert-butyl-1-benzopyrilium perchlorate with various reducing agents leads to a mixture of 2H- and 4H-chromenes.The greatest selectivity (90percent 2-tert-butyl-4H-chromene and 10percent 2H-isomer) was achieved using 1,3-dimethylbenzimida

Enantioselective synthesis of 2,3-disubstituted: Trans -2,3-dihydrobenzofurans using a Br?nsted base/thiourea bifunctional catalyst

The diastereo- and enantioselective synthesis of 2,3-disubstituted trans-2,3-dihydrobenzofuran derivatives (15 examples, up to 96 : 4 dr, 95 : 5 er) via intramolecular Michael addition has been developed using keto-enone substrates and a bifunctional tertiary amine-thiourea catalyst. This methodology was extended to include non-activated ketone pro-nucleophiles for the synthesis of 2,3-disubstituted indane and 3,4-disubstituted tetrahydrofuran derivatives.
