摘要

The synthesis of racemic 2, 3, 4, 5, 6, 6a-hexahydro-3-methyl-3-hydroxy-1H-4, 1lb- methanobenzofuro [3, 2-d] azocine (2) is described. The route utilized a key photochemical conversion of the aryloxy enone 7 to the hexahydrodibenzofuran 8, which established the relative stereochemistry of the oxide and methano bridges of 2. A 1, 4-Michael-type addition of nitrogen to the@-carbon of the a,@-unsaturated compound 12 establishedthe fourth ...
