Enyne alcohols can react as precursors of either dienes or dienophiles with different substrates after hydroxylation and isomerization by gold catalysis. As such, oxa-bridged tricyclo[5.2.2.02,6]-undec-8-ene-3,5-dione derivatives have been obtained by the Diels–Alder reaction and tetrahydro-1H-furo[3,4-c]pyran derivatives could be accessed by the hetero-Diels–Alder cycloaddition.
烯炔醇通过金催化羟化和异构化后,可以作为二烯或二烯亲和物的前体与不同的底物反应。因此,通过狄尔斯-阿尔德反应和四氢-1H-呋喃[3,4-c]吡喃获得了氧杂桥联的三环[5.2.2.02,6]-十一碳-8-烯-3,5-二酮衍生物。杂Diels-Alder环加成可以访问派生类。
