(+)-Steganacin was synthesized in a new and highly specific asymmetric pathway based on the novel application of chiral γ-lactone as a chiral synthon. By this synthesis the absolute stereochemistry of natural (−)-steganacin could be determined in unequivocal way.
(+)-替加那星是基于手性γ-内酯作为手性合成子的新应用,以一种新的,高度特异性的不对称途径合成的。通过这种合成,可以以明确的方式确定天然(-)-steganacin的绝对立体
