In relation to the syntheses of exo- and endo-calixnaphthalenes, the chemical reactions of several 2- and 3-hydroxymethylnaphthols, as well as other substituted naphthols, with formaldehyde under a variety of condensation reaction conditions were evaluated. In several instances, o-naphthoquinomethides were the putative intermediates which were formed and which resulted in hetero-Diels–Alder [4+2]cyclodimerization
