The influence of high pressure (in the kbar region) on the outcome of the Au(I)-catalyzed cycloisomerization of 1,6- and 1,7-enynes is presented. The positive effect of pressure is particularly marked for reactions involving sterically biased substrates (e.g. 1,6-enynes bearing atert-butyl substituent at the alkyne moiety) and the challenging cyclization of internal 1,7-enynes.
介绍了高压(在 kbar 区域)对 Au(I) 催化的 1,6- 和 1,7-烯炔环异构化结果的影响。压力的积极影响对于涉及空间偏向底物(例如在炔部分带有叔丁基取代基的 1,6-烯炔)和内部 1,7-烯炔的具有挑战性的环化的反应尤其显着。
