developed [4+3]IMPC (intramolecular parallel cycloaddition) of cyclopropane 1,1‐diesters with [3]dendralenes. With a combination of the [4+3]IMPC and subsequent [4+n] cycloadditions, trans‐[5.3.0]decane skeleton and its corresponding structurally complex and diverse polycyclic variants could be constructed efficiently. This novel [4+3] cycloaddition reaction mode of donor–acceptor cyclopropanes proceeds
为了开发用于构建复杂多样的多环骨架的有效且通用的策略,我们成功开发了[4 + 3] IMPC(分子内平行环加成)环丙烷1,1-二酯与[3]树枝状分子。结合[4 + 3] IMPC和随后的[4 + n ]环加成反应,可以有效地构建反式-[5.3.0]癸烷骨架及其相应的结构复杂和多样的多环变体。这种新的供体-受体环丙烷的[4 + 3]环加成反应模式是由于反式[3.3.0]辛烷的环应力释放而产生的。我们坚信所开发的方法将证明其在天然产物合成和药物开发中的潜在应用。
