Abstract
Abstract Oxaellipticine has been synthesized from 1, 4-dimethyldibenzofuran, by converting it to the 2-aldehyde, forming the Schiff's base with aminoacetaldehyde diethyl acetal, and cyclizing this with 105% superphosphoric acid. Alternatively, tetrahydrodimethyldibenzofuran was formylated mainly at the 3-position, and the 3-(2- nitrovinyl) derivative of the 3-aldehyde, by hydride reduction, then Bischler-Napieralski ...
