Wang, Min Liu, Zheng-Li Zhang, Xiang Tian, Pan-Pan Xu, Yun-He Loh, Teck-Peng Synthesis of Highly Substituted Racemic and Enantioenriched Allenylsilanes via Copper-Catalyzed Hydrosilylation of (<i>Z</i>)‑2-Alken-4-ynoates with Silylboronate Copper-catalyzed highly efficient hydrosilylation reaction of enynoates was developed. Under simple reaction conditions, various di-, tri-, and tetrasubstituted racemic allene products could be obtained in high yields. The asymmetric 1,6-addition of silyl group to the (<i>Z</i>)-2-alken-4-ynoates could be achieved under mild reaction conditions to afford the silyl-substituted enantioenriched chiral allene products in good yields and with high enantioselectivities. reaction conditions;yield;tetrasubstituted racemic allene products 2015-12-02
