WebMay 30, 2024 · The next step required the isomerisation of internal alkyne 15 using the alkyne zipper reaction. Fortuitously, our initial choice of n-butyllithium, potassium tert-butoxide and 1,3-diaminopropane in tetrahydrofuran proved highly effective for this transformation. Accordingly, 15 was converted to terminal alkyne 16 in 96% yield. WebVic's Alterations is a locally owned business in Eagan MN. Our staff provides the.
