A second-generation synthesis of polypyrrolinone nonpeptidomimetics: prelude to the synthesis of polypyrrolinones on solid support.

[reaction: see text] A second-generation asymmetric synthesis of polypyrrolinones (3) has been achieved exploiting scalemic alpha-aminolactones (1) as building blocks. Imine formation between an appropriate lactone (1) and aldehyde (2), followed in turn b
