An efficient synthetic method of Z-selective 3-ethoxycarbonyl-2-halo-1,3-dienes and 3-vinyl-2-halo-1,3-dienes was developed from the reaction of allenols having ethoxycarbonyl and vinyl group with indium trihalides at room temperature in $CH_2Cl_2$.
在 $CH_2Cl_2$ 中,具有乙氧羰基和乙烯基的烯醇与三卤化铟在室温下发生反应,从而开发出一种高效的 Z 选择性 3-乙氧羰基-2-卤-1,3-二烯和 3-乙烯基-2-卤-1,3-二烯的合成方法。

A novel copper-catalyzed asymmetric Doyle-Kirmse of azide-ynamides via α-imino copper carbenes is disclosed, enabling the practical and divergent assembly of chiral [1,4]thiazino [3,2-b]indoles in generally moderate to excellent yields and excellent enantioselectivities. This protocol represents the first asymmetric Doyle–Kirmse reactionvia a non-diazo approach and the first asymmetric [2,3]-sigmatropic
