Popis: |
Of the 16 possible modes of the oxidation-6π-electrocylization-Diels–Alder reaction cascade for an epoxyquinone, and eight for a 2-alkenyl-3-hydroxymethyl-2-cyclohexen-1-one, only the endo - anti (epoxide) -anti (Me)-hetero and endo - anti (Me)-hetero are respectively observed, while both the endo - anti (epoxide) -anti (Me)-hetero and exo - anti (epoxide) -anti (Me)-homo reaction modes occur with epoxy-4-hydroxycyclohexenones owing to a hydrogen-bonding interaction. |
