Regioselective Synthesis of Highly Substituted Naphthols
摘要:
2,3,4-Trisubstituted 4-hydroxy-2-cyclobutenones, prepared by regiospecific synthesis of substituted cyclobutenediones, undergo Lewis acid facilitated ionization to cyclobutenyl cations, which are trapped by trialkylsilanes in a regioselective sense. Thermolysis of the resulting cyclobutenones affords phenols in high yields.
