The assignment of absolute configurations by NMR of arylmethoxyacetate derivatives: is this methodology being correctly used? by José Manuel Seco; Emilio Quiñoá; Ricardo Riguera is a Chemistry article available to read on EtoBox.

What is The assignment of absolute configurations by NMR of arylmethoxyacetate derivatives: is this methodology being correctly used? about?

Examples in which Mosher's method does not allow a safe con®gurational assignment of absolute con-®guration are presented. This situation occurs when: (a) L 1 and L 2 show identical signs of Ád SR ; (b) when both positive and negative Ád SR values coexist for the same substituent; (c) only NMR data from one substituent of L 1 or L 2 is available; and (d) when polyalcohols are treated like monoalcohols. The requirements for the correct application of this method are discussed.
