Using 1 -chloro-l-[~~N]nitrosocyclohexane, we have prepared five L-[a-'SN]arnino acids. The stereoselective electophillic hydroxyamination of (S)-acylbornane-l0,2-suftams, followed by ZnO/H+ reduction, and alkaline cleavage of the chiral auxiliary, gave the amino acids in 97.2-99.5 % e.e. By starti
We describe methods to introduce 13 C specifically to the C2 or C8 positions of 15 N-multilabeled purines, thereby permitting " 13 C tagging" of all base nitrogens except the amino group of adenosine. These procedures permit the incorporation of two or more 15 N-multilabeled monomers into a given DN
