Organocatalytic double Michael reaction and the subsequent aldol condensation of (E)-7-oxooct-5-enal and 3-arylpropenal (e.g., cinnamaldehyde) provided octahydro-6-oxo-1-phenylnaphthalene-2-carbaldehyde in high diastereoselectivity and high enantioselectivity (>99% ee). Structures of the adducts 5a and 5j were confirmed unambiguously by X-ray analysis.
有机催化双迈克尔反应以及随后的(E)-7-氧代辛基-5-烯醛和 3-芳基丙烯醛(如肉桂醛)的醛醇缩合反应以高非对映选择性和高对映选择性(>99% ee)提供了八氢-6-氧代-1-苯基萘-2-甲醛。加合物 5a 和 5j 的结构通过 X 射线分析得到了明确证实。
