- Forms tetrahydrofuranyl esters (acyl hemiacetals) with carboxylic acids. These react with Grignard reagents to give good yields of ketones with minimal enolization or double addition (tertiary alcohol formation). The utility of other acyl hemiacetals as ketone precursors has also been studied: J. Org. Chem., 61, 6071 (1996):
