Kh. Park et Mj. Kurth, Solid-phase synthesis of novel achiral hydantoin- and isoxazoline-substituted dispirocyclobutanoids, CHEM COMMUN, (19), 2000, pp. 1835-1836
A synthesis of novel achiral hydantoin- and isoxazoline-substituted dispiro
cyclobutanoids from solid-phase synthesis has been achieved. The facial and
selective Boc-NH-mediated hydrogen-bond delivery of the nitrile oxide affo
rded 6 as the major compound.
