transformation of D-glucal to (2R)-hydroxymethyldihydropyridinone 5 in seven steps and 35 % overall yield is reported. Dihydropyridone 5 constitutes a versatile chiral building block for the synthesis of various piperidine alkaloids. In this regard, 5 was converted to piperidinol 13 and piperidinone 15, that may be further elaborated for the syntheses of (+)-desoxoprosophylline (1) and deoxymannojirimycin (3)
据报道,D-葡糖醛分七步有效转化为 (2R)-羟甲基二氢吡啶酮 5,总产率为 35%。二氢吡啶酮 5 是合成各种哌啶生物碱的通用手性构件。在这方面,5 被转化为哌啶醇 13 和哌啶酮 15,它们可以分别用于 (+)-desoxoprosophylline (1) 和 deoxymannojirimycin (3) 或 D-甘露内酰胺 (4) 的合成。
