The gold(I)-catalyzed [2 + 2] cycloaddition of large 1,n-enynes (n = 10-16) provides access to 9- to 15-membered ring macrocycles incorporating a cyclobutene moiety. The reaction requires the use of a gold(I) catalyst bearing a sterically hindered biphenylphosphine ligand.
金(I)催化的大 1,n-烯炔(n = 10-16)[2 + 2]环加成反应可得到包含环丁烯部分的 9 至 15 元环大环化合物。该反应需要使用带有空间位阻联苯膦配体的金(I)催化剂。
