Over the past few decades,the C-B bond formation has drawn substantial attention in organic synthesis due to the diverse chemical reactivities of boron compounds.Among largely reported methodologies,copper-catalyzed hydroboration reaction is particularly important,because unsaturated substrates and diborons (B2pin2) both involved in this catalytic process.1,2 However,the untilzation of terminal and α-vinyl(pinacolato)borons as substrates in this reaction is still limited Herein,a copper-catalyzed hydroboration of alkynes in aqueous medium is reported.This approach is the first report of regioselective hydroboration of alkynes regiocontrolled by cyclodextrin (CD) derivative and it enables the efficient access to obtain vinyl boronates from simple terminal alkynes.

喹啉骨架是一类具有生物活性的含氮的杂环化合物，广泛的存在于天然产物和人工合成的药物中，它的合成受到有机化学家和药物化学家的广泛关注。虽然众多方法已经用于该类化合物的合成，但传统的合成方法通常需要苛刻的反应条件、预活化的底物，从而限制了其广泛应用。近年来，随着C-H键活化的研究，通过C-H键的直接功能化，提高了有机反应的效率，减少了合成步骤，为功能有机分子的合成提供了新的途径。在本课题组近年来通过对
