New thiophosphates containing functionalized cyclic ketone derivatives as ligands have been stereoselectively prepared from readily available starting materials. Full axial stereoselectivity of the NaBH4 reduction of the carbonyl group in thiophosphates providing the corresponding thiols or sulfides has been demonstrated. The sulfides have been transformed into new functionalized cyclic Baylis–Hillman type adducts of defined configuration. The prospects for the useful synthetic application of these adducts appear to be very promising.
含有官能化环酮衍生物作为配体的新硫磷酸酯已从易得的起始材料中立体选择性地合成。已经证明,NaBH4对硫磷酸酯中羰基的还原反应具有完全的轴向立体选择性,生成相应的硫醇或硫化物。这些硫化物已被转化为具有明确定型的新型官能化环状Baylis–Hillman型加合物。这些加合物在有用合成应用方面的前景看起来非常可观。
