Synthesis of benzofused cyclobutaoxepanones via intramolecular annulation of o-cinnamyl chalcones.

Published in: Organic & biomolecular chemistry (2021)

Intramolecular stereoselective annulation of o-cinnamyloxy chalcones provides two kinds of tricyclic benzofused cyclobutaoxepanones via the synthesized routes of DABCO/NBS (1,4-diazabicyclo[2.2.2]octane/N-bromosuccinimide)-mediated Baylis-Hillman type cyclization or low-pressure mercury (LP Hg) lamp-promoted photocontrolled [2 + 2] cycloaddition. Diversified reaction conditions have been investigated for one-pot facile, high-yield transformation.
