Abstract
Synthetic utility of trimethyl and triethyl orthoformates for carbon-carbon bond formation is briefly surveyed, particularly in relation to dialkoxymethylation, carbonyl transposition-homologation, and cycloalkenone annulation reactions recently reported from the authors’ and other laboratories. The complex mechanisms involved in the one-step and two-step annulations of rigid β,γ- and γ, δ-unsaturated ketones have been discussed.
