Eschenmoser’s sulfur extrusion

Barton olefinations, 35 Eschenmoser s sulfur extrusion, 59-60, 261 ThioacCtals. See 1,3-Dithianes 1,3-Dithiolanes ... [Pg.222]

Scheme 28 outlines Eschenmoser s model corrin synthesis. The enamide (310) was treated with KCN to give (311), and this gave the thiolactam (312) when treated with phosphorus pentasulfide. Benzoyl peroxide oxidation yielded the disulfide (313), and in the presence of the enamide (310) this gave the bicyclo thio-bridged compound (314). Sulfur extrusion, by this time a standard procedure (Scheme 22), provided the vinylogous amidine (315)... [Pg.428]
