Yu, C., Y.-Y. Tseng, and S.-S. Lee Calculating Three-dimensional Molecular Structure of Paliurine B from Atom-Atom Distance and Restrained Energy Minimization. Biochim. Biophys. Acta, 1156, 334 (1993). [Pg.175]

Amidations of vinyl iodides have also been used to advantage in synthesis. Enamides such as 50-52 are representative of the procedures available (Scheme 1-3). By proper choice of nucleophile, annulations to either pyrroles 54 (15 examples) or pyrazoles 55 (10 examples) can be induced with Cul-catalysis after an initial amidation of enyne 53. " Subsequent 5-endo-dig cyclization produces the heteroaromatic products (Scheme 1-4). Several total syntheses have successfully applied this approach, as examples, to construction of key enamide antibiotic CJ-15,801 (56), and the naturally occurring cyclopeptide alkaloid paliurine F (57), where this methodology served as a tool for macrocyclization.
