DOCUMENT TYPE: Journal CA Section: 34 (Amino Acids, Peptides, and Proteins) Section cross-reference(s): 22, 35 The first example of magic angle spinning NMR on crowns has been demonstrated. The ability to monitor a reaction on a crown and to confirm the structure of the reaction product directly on the crown without resorting to chem. cleavage should greatly enhance the utility of this convenient format for combinatorial chem. .
