Stable and readily available N,N′-di-Boc-substituted thiourea, when activated with trifluoroacetic acid anhydride, was used as a novel thioacylating agent. Through the thioacylation of nucleophiles, such as amines, alcohols, thiols, sodium benzenethiolate, and sodium malonates with N,N′-di-Boc-substituted thiourea, a series of thiocarbonyl compounds were prepared under mild conditions with good chemical selectivity and functional group tolerance.
稳定且易于获得的N,N′-双-Boc取代硫脲,在三氟乙酸酐活化下,被用作一种新型硫代酰化剂。通过对亲核试剂如胺、醇、硫醇、苯硫醇钠和丙二酸钠与N,N′-双-Boc取代硫脲的硫代酰化反应,一系列硫代羰基化合物在温和条件下以良好的化学选择性和官能团耐受性被制备出来。
