The synthesis of a new pentacovalent oxaphospholene from a dienone, and its use as an enolate equivalent in the approach toward the syntheses of a phosphonate analog of sphingomyelin, sphingosine 1-phosphate and ceramide 1-phosphate is described. Condensation of the new P(V) reagent with an azodicarboxylate, followed by reduction of the ketone produced cis- and/or trans-oxazolidinones, potential precursors
描述了由二烯酮合成新的五价氧杂磷腈及其在鞘磷脂,1-磷酸鞘氨醇和1-磷酸神经酰胺的磷酸酯类似物的合成中作为烯醇式等同物的用途。新的P(V)试剂与偶氮二羧酸酯缩合,然后还原酮,生成顺式和/或反式-恶唑烷酮,这是鞘磷脂,鞘氨醇和神经酰胺分子的潜在前体。提出了一种还原剂以产生所需的顺式-恶唑烷酮的研究。
