Broadrup, Robert L.,Wang, Bei,Malachowski, William P.
, p. 10277 - 10284 (2007/10/03)
A selection of azapeptidomimetics containing constraining lactam rings have been prepared by Mitsunobu cyclization of serine/homologated serine-azaalanine derivatives. These include sterically-congested β-lactams, as well as γ-butyrolactam and δ-valerolac
