Racemic 4-hydroxycyclopentenone, readily derived from furfuryl alcohol, can be transformed via its O-Boc derivative to 4-acyloxy, 4-aryloxy-, 4-amino-, or 4-thio-substituted cyclopentenones with high enantioselectivity by palladium-catalyzed kinetic resolution via nucleophilic allylic substitutions. Applying this methodology, a short formal synthesis of ent-noraristeromycin was readily accomplished
易于衍生自糠醇的外消旋4-羟基环戊烯酮可通过其O -Boc衍生物通过钯催化的动力学以高对映体选择性转化为4-酰氧基,4-芳氧基-,4-氨基-或4-硫基取代的环戊烯亲核烯丙基取代解决。应用这种方法,短正式合成耳鼻喉科-noraristeromycin容易地完成。
