demonstrated that amides can be used in nickel‐catalyzed reactions that lead to cleavage of the amide C−N bond, with formation of a C−C or C−heteroatom bond. However, the general scope of these methodologies has been restricted to amides where the carbonyl is directly attached to an arene or heteroarene. We now report the nickel‐catalyzed esterification of amides derived from aliphatic carboxylic acids

Bryostatins: The Asymmetric Synthesis of the C<sub>1</sub>-C<sub>9</sub>and C<sub>17</sub>-C<sub>27</sub>Fragments

The construction of the fragments C1-C9 3 and C17-C27, 4a of the bryostatins in a enantioselective and highly diastereoselective fashion is described. The usefulness of the "chiron" approach is illustrated with the synthesis of these fragments from, respectively, D-pantolactone (6) and D-isobutyl lactate (23) as chiral templates.
