Synthesis of the C1-C13 fragment of kendomycin: Atropisomerism around a C-aryl glycosidic bond

The left-hand fragment 2 of the novel antibiotic kendomycin (1) has been synthesized by an aldol addition of a C5 alcohol with a C9-C11 enone. Compound 2 shows an interesting atropisomerism around the C4a-C5-sp2-sp3 bond. The atropis
