Abstract
Collective total syntheses of oboflavanones A-B, cryptoflavanones C-D, and cryptoyunnanones G-H via a bioinspired acid-triggered olefin isomerization/hemiacetalization/dehydration/formal [3 + 3]-type cycloaddition cascade process are presented.

Abstract
![]()
Multiconfigurational
complete active space methods (CASSCF and
CASPT2) have been used to investigate the (4 + 2) cycloadditions of
allene with butadiene and with benzene. Both concerted and stepwise
radical pathways were examined to determine the mechanism of the Diels–Alder
reactions with an allene dienophile. Reaction with butadiene occurs
via a single ambimodal transition state that can lead to either the
concerted or stepwise trajectories along the potential energy surface,
while reaction with benzene involves two separate transition states
and favors the concerted mechanism relative to the stepwise mechanism
via a diradical intermediate.
