The absolute stereochemistry of TT-1 (1=rasfonin), an α-pyrone-containing natural product from a Fungi Imperfecti, Trichurus terrophilus, was determined as 5R,6R,7S,9R, and 6′S on the basis of synthesis of diastereomers of two fragments of 1 in optically active forms, and comparison of their spectral and optical data with those of natural specimens.
TT-1(1 = rasfonin)的绝对立体化学,是一种来自不育真菌Trichurus terrophilus的含α-吡喃酮的天然产物,被确定为5 R,6 R,7 S,9 R和6 'S。合成两个光学活性形式的1片段的非对映异构体的基础,并将其光谱和光学数据与天然样品进行比较。
