Disclosed are enantioselective cross dehydrogenative coupling reactions for synthesizing tetrahydropyran compounds. Novel tetrahydropyran compounds may be synthesized by the disclosed methods as well as tetrahydropyran precursor compounds for synthesizing various naturally occurring compounds. The enantioselective cross dehydrogenative coupling reactions utilize in situ Lewis Acid activation in combination with oxidative formation of an oxocarbenium ion to provide a highly efficient and selective coupling reaction for synthesizing tetrahydropyran compounds.

An enantioselective cross-dehydrogenative coupling (CDC) reaction to access tetrahydropyrans has been developed. This process combines in situ Lewis acid activation of a nucleophile in concert with the oxidative formation of a transient oxocarbenium electrophile, leading to a productive and highly enantioselective CDC. These advances represent one of the first successful applications of CDC for the
