The α-hydroxy-o-quinodimethanes were generated by thermal electrocyclic ring-opening reaction of benzocyclobutenols, the photolysis of o-alkylsubstituted benzaldehydes, thermal cheletropic reaction of α-hydroxy dihydrobenzothiophene dioxides, and 1,4-elimination from o-(α-stannylmethyl)benzaldehydes. Examples from benzocyclobutenols:

note
-
When the zinc alkoxide was formed completely by the reaction of benzocyclobutenol 1A and the reactive isopropylzinc reagent for an appropriate reaction time, the enantioselectivity might be enhanced.

note

When the interval without a dienophile was too long, the production of a slight amount of a by-product 12, which might have disturbed the ideal reaction pathway, was confirmed. Although the mechanism of the production of 12 was not clear yet, a possible pathway is shown in the following scheme.{A figure is presented}
