  Au(I) catalyzes the transformation of alkynes into cyclic acetals and thioacetals at much higher rate than Brønsted acids. The reaction appears to be general for a range of alkynes and diols or dithiols, which are efficiently transformed with high selectivities. One of the salient features of this reaction process is the high reactivity of the enol ether or enol thioether intermediates, which undergo

  Au（I）以比布朗斯台德酸高得多的速率催化炔烃向环状缩醛和硫缩醛的转化。对于一系列炔烃和二醇或二硫醇，该反应似乎是普遍的，这些炔烃和二醇或二硫醇以高选择性被有效地转化。该反应过程的显着特征之一是烯醇醚或烯醇硫醚中间体的高反应性，它们进行快速异构化反应以提供环状缩醛或硫缩醛，因此不需要分离或随后的活化过程。这种类型的反应使我们能够合成一系列香料。
