hexadehydro-Diels–Alder reaction of substrates containing tethered trapping moieties. Products having new structural motifs can be created. (i) Medium-sized fused rings can be produced by varying the length of the tether. (ii) The tether can emanate from an atom within the linker unit that joins the 1,3-diyne and diynophile. (iii) The importance of the rate of trapping by the benzynophile is established.
此处报道的研究已经确立了含有束缚捕集部分的底物的六氢-狄尔斯-阿尔德反应的新特征。可以创建具有新的结构图案的产品。(i)可以通过改变系链的长度来制造中型稠环。(ii)系链可以从连接1,3-二炔和二嗜亲核分子的连接器单元内的原子发出。(iii)确定了苯并嗜性菌捕获速度的重要性。
