The phosphine-catalyzed (3+3) annulation reaction of cinnamaldehyde-derived Morita–Baylis–Hillman (MBH) carbonates with 1,3-dicarbonyl compounds as dinucleophiles has been developed, giving hexahydrochromenone derivatives in high yields with moderate to good diastereoselectivities. The reaction worked through double conjugate addition of 1,3-dicarbonyl compounds to the phosphonium intermediates generated
已经开发出肉桂醛衍生的 Morita-Baylis-Hillman (MBH) 碳酸酯与 1,3-二羰基化合物作为双亲核试剂的膦催化 (3+3) 成环反应,以高产率产生具有中等至良好非对映选择性的六氢色烯酮衍生物。该反应通过 1,3-二羰基化合物与肉桂醛衍生的 MBH 碳酸酯生成的鏻中间体进行双共轭加成来进行。
