The highly enantio- and regioselective copper catalyzed asymmetric propargylation of aldehydes with a propargyl borolane reagent is reported. The methodology demonstrated broad functional group tolerance and provided high enantioselectivities for aliphatic, vinyl, and aryl aldehydes. The utility of the TMS homopropargylic alcohols was demonstrated by the facile conversion to a chiral dihydropyranone
报告了高度对映和区域选择性的铜催化醛与炔丙基硼烷试剂的不对称炔丙基化。该方法证明了广泛的官能团耐受性,并为脂肪族、乙烯基和芳基醛提供了高对映选择性。TMS 高炔丙醇的效用通过轻松转化为手性二氢吡喃酮来证明。
