2,3,5,6-Tetrahydro-6-oxo-1H-pyrrolizines, which are potential precursors of 2,3-dihydro-1H-pyrrolizines, were synthesized by a smooth thermal acid-promoted bicyclization of Ï-acetylenic aminoesters.

ML-3000 was obtained from 1-chloro-3-phenyl-2-propyne in 8 steps with an overall yield of 19%. The key steps are a thermal acid-promoted bicyclization of an ω-acetylenic amino ester and a Suzuki cross-coupling reaction between a heteroaryl triflate and (4-chlorophenyl)boronic acid.
