Imide reduction

WitrynaThe reduction of alkynes with diimide has been reviewed < 91COS(8)471 >. This reduction has been known for many years and remains a most simple and elegant way of reducing a triple bond to a (Z)-alkene with high stereospecificity and chemoselectivity. The reduction with diimide is extremely chemoselective tolerating ester, amide, and …
