Differentiation of enantiotopic carbonyl groups by the horner-wadsworth-emmons reaction
摘要:
A chiral phosphonoacetate 2 differentiates the enantiotopic carbonyl groups in an alpha-diketone 5 to afford the Z-olefin 6 in high yield and ee. The absolute stereochemistry of 6 was determined by X-ray analysis of 8 derived from 6.
