Enhanced enantio- and diastereoselectivities via confinement: photorearrangement of 2,4-cyclohexadienones included in zeolites.
[reaction: see text] Employing zeolite as the reaction medium, it is possible to change the enantio (from achiral dienones) and diastereo (from chiral dienones) selectivities during the oxa-di-pi-methane rearrangement of 2,4-cyclohexadienones.
