资源简介:
A novel strategy to synthesize 1,3-enynes has been successfully developed based on Cu­(I)-catalyzed cross-coupling of α-diazo phosphonates and alkynes with a subsequent Horner–Wadsworth–Emmons (HWE) type reaction. This method provides straightforward access to conjugated enynes with high efficiency, good stereoselectivity and excellent functional group compatibility. Copper­(I) carbene migratory insertion plays a crucial role in this transformation.
