Formal Synthesis of Leustroducsin B via Reformatsky/Claisen Condensation of Silyl Glyoxylates
摘要:
A formal synthesis of leustroducsin B has been completed. The synthesis relies upon a recently developed Reformatsky/Claisen condensation of silyl glyoxylates and enantioenriched beta-lactones that establishes two of the molecule's three core stereocenters and permits further elaboration to an intermediate in Imanishl's synthesis via reliable chemistry (Prasad reduction, asymmetric pentenylation, Mitsunobu inversion).
