Acid-Catalyzed Aza-Diels−Alder Reactions for the Total Synthesis of (±)-Lapatin B
摘要:
A 5-step total synthesis of microfungal alkaloid (+/-)-lapatin B has been accomplished via a key 2-aza-Diels-Alder reaction. Bronsted acids catalyze the cycloaddition step and provide improved exo selectivity. This synthetic route has been applied to the construction of related spiro-quinazoline structures.
