Abstract
Abstract 1, 3-Dienyl ethers and the corresponding sulfides (CH 2 [DOUBLE BOND] CH [BOND] CH [DOUBLE BOND] CH [BOND] XR; X [DOUBLE BOND] O, S; R [DOUBLE BOND] alkyl, phenyl) are readily metallated at C-1, using n-butyllithium and KO-t-Bu in tetrahydrofuran. 2H-Thiopyran can be lithiated at the 6-position with n-butyllithium and tetramethylethylenediamine in tetrahydrofuran. The various metallated compounds react ...
