Toward the Synthesis of Spirastrellolide A: Construction of a Tetracyclic C26−C40 Subunit Containing the DEF-Bis-Spiroacetal
摘要:
A stereocontrolled synthesis of the fully elaborated C-26-C-40 tricyclic [5,6,6]-bis-spiroacetal of spirastrellolide A containing the C-28 chlorine substituent is reported, exploiting asymmetric Sharpless dihydroxylation and boron-mediated allylation methodology.
