Solid-phase synthesis of novel achiral hydantoin- and isoxazoline-substituted dispirocyclobutanoids
摘要:
A synthesis of novel achiral hydantoin- and
isoxazoline-substituted dispirocyclobutanoids from solid-phase synthesis
has been achieved. The facial and selective Boc-NH-mediated hydrogen-bond
delivery of the nitrile oxide afforded 6 as the major compound.
