Palladium-catalyzed C1-vinylation of β-naphthols with α-trifluoromethyl allyl carbonates: One-pot access to naphtho[2,1-b]furans
Highly regio- and stereoselective palladium-catalyzed C1-vinylation of β-naphthols (2) has been reported using easily accessible CF3-allyl carbonates (1). The regioselective nucleophilic -attack of CF3-π-allyl-Pd-intermediate is the key to furnish (Z)-CF3-vinylnaphthols...
