摘要：
The enantioselective total synthesis of the putative structure of versiquinazoline H and three diastereomers has been achieved, which allowed the revision of the stereochemistry of this natural product. This six-step total synthesis relied on the evolution of the strategy that we previously developed, which features a DMDO-triggered tandem reaction. The modification of the lactamization step resulted in a significant improvement of yield that ensured the efficient total synthesis.
