Convergent, stereoselective syntheses of the pharmacologically active, naturally occurring lactones (−)-microcarpalide and (+)-lethaloxin have been achieved from the commercially available, chiral reagents (R)-glycidol, (S,S)-tartaric acid, and d-ribose as the starting materials. These syntheses have further served to establish the hitherto unknown absolute configuration of (+)-lethaloxin and to show
从市售的手性试剂(R)-缩水甘油,(S,S)-酒石酸和d -核糖为起始原料。这些合成进一步用于建立迄今未知的(+)-氧氟沙星的绝对构型,并显示其与(+)-血脂毒素的身份。
