Significance

A 90-membered library of indoline-alkaloid-like polycyclic compounds was synthesized through stereoselective hetero-Michael reactions with nitrogen nucleophiles as the key step. The seven synthetic steps on the solid-support were carried out under very mild conditions to give the library members in high yields (80-85%).

Comment

Solid-phase synthesis is an effective tool to prepare libraries of drug candidates in a high-throughput manner. The present method can easily introduce the four diversity sites into an indoline-alkaloid-like tricyclic backbone by employing mild conditions, which are appropriate to explore and generate a molecule library.
