  Synthesis of the C1-C13 Fragment of Kendomycin: Atropisomerism around a C−Aryl Glycosidic Bond

  摘要：

  The left-hand fragment 2 of the novel antibiotic kendomycin (1) has been synthesized by an aldol addition and a Michael-type 1,4-addition of a C5 alcohol with a C9-C11 enone. Compound 2 shows an interesting atropisomerism around the C4a-C5-sp2 -sp3 bond. The atropisomers can be separated in pure forms by low-temperature high-pressure liquid chromatography.
