A Ni-catalyzed (4 + 2) cycloaddition of alkynes and azetidinones toward piperidinones was used as key reaction in the enantioselective synthesis of naturally occurring indolizidine alkaloids. The reaction benefits from the use of an easily accessible azet

We describe here an efficient synthesis of both diastereomers of cyclic β,γ-diamino acids starting from l-glutamic acid, based on the Blaise reaction. We show that by changing the protecting group, we can access either the five-membered-ring lactam, which
