Synthetic studies related to the esperamicin/calicheamicin aglycone: efficient construction of a homochiral oxabicyclo [7 : 3 : 1] analogue from D-xylose
Abstract
The synthesis of a bicyclic model of the calicheamicin/esperamicin aglycone is described using a highly efficient and stereospecific Nozaki–Kishi reaction for the ring closure.
