Abstract

Four out of the five rings of the alkaloid neotuberostemonine (1) are present in the advanced precursor 2. The tetracyclic compound 2 has now been prepared in a short, linear route via lactone acid 3. A key step in the synthesis was the cuprate-mediated S_N2′ ring-opening desymmetrization of the C₂-symmetric bislactone 4.
