We describe a synthetic pathway to structurally complex and diverse polyketides based, in part, on regio- and stereoselective titanium-mediated coupling reactions. The sequences described allow for rapid assembly of polyketide-inspired architecture while providing significant flexibility for the establishment of diverse stereochemical relationships and substitution patterns along the carbon backbone (including stereodefined alkenes and 1,3-dienes, saturated and unsaturated lactones, hemiketals, α,β-unsaturated carbonyls, and spiroketals).
我们描述了一条合成路径,用于合成结构复杂且多样的多酮类化合物,部分基于区位和立体选择性的钛介导耦合反应。所描述的合成序列允许快速组装多酮类启发的结构,同时在碳主链上建立多样的立体化学关系和取代模式(包括立体定义的烯烃和1,3-二烯、饱和和不饱和内酯、半缩醛、α,β-不饱和碳基化合物以及螺环醇)。
