Enantioselective Synthesis of Metathesis-Derived Ureapeptoid Macrocycles

Wang, Xiang-Zhu,Burke Jr., Terrence R.

, p. 469 - 472 (2007/10/03)

Ring-closing metathesis (RCM) was used for the preparation of the first member of a new class of ureapeptoid-containing macrocycles. Key to the approach was the enantioselective synthesis of functionalized carbamoyl alkenylglycine equivalents using (-)-B-allyldiisopinocampheylborane [(-)-d-Ipc2Ball]-mediated asymmetric allylation.
