Abstract
AbstractHighly functionalized chiral furo‐pyrrolizidinones containing contiguous quaternary centers were synthesized in moderate to good yields by treatment of various hexahydro‐3,4‐dioxa‐8a‐aza‐as‐indacen‐2‐ones with m‐CPBA under basic conditions through a tandem Cope elimination/1,3‐dipolar cycloaddition reaction sequence, followed by N–O cleavage and lactam ring cyclization.
