  • METAL-CATALYZED ASYMMETRIC 1,4-CONJUGATE ADDITION OF VINYLBORON COMPOUNDS TO 2-SUBSTITUTED-4-OXY-CYCLOPENT-2-EN-1-ONES YIELDING PROSTAGLANDINS AND PROSTAGLANDIN ANALOGS

    This invention provides a novel method for the preparation of 2,3-disubstituted-4-oxy-cyclopentan-1-one compounds that are useful for the synthesis of prostaglandins and prostaglandin analogs of industrial relevance. The method comprises the metal-catalyzed asymmetric 1,4-conjugate addition of vinylboron compounds to 2-substituted-4-oxy-cyclopent-2-en-1-ones. This method relies on the use of less toxic, easily-handled reagents, and can be performed under milder conditions than offered by some conventional methods, affording 2,3-disubstituted-4-oxy-cyclopentan-1-one compounds enantio- and diastereoselectively, which are precursors to the said prostaglandin and prostaglandin analogs, in high yield.
    本发明提供了一种新的方法,用于制备2,3-二取代-4-氧基-环戊烷-1-酮化合物,这些化合物对于合成工业相关的前列腺素和前列腺素类似物非常有用。该方法包括金属催化的不对称1,4-共轭加成反应,将乙烯基硼化合物加到2-取代-4-氧基-环戊-2-烯-1-酮上。该方法依赖于使用毒性较小、易于处理的试剂,并且可以在比某些传统方法提供的温和条件下进行,选择性地制备2,3-二取代-4-氧基-环戊烷-1-酮化合物的对映体和立体异构体,这些化合物是所述前列腺素和前列腺素类似物的前体,收率高。
