This is the first of five books in the *Amino Acids, Peptides and Proteins in Organic Synthesis* series. Closing a gap in the literature, this is the only series to cover this important topic in organic and biochemistry. Drawing upon the combined expertise of the international "who's who" in amino
## Abstract Sulbactam, a Ξ²βlactamase inhibitor, has been prepared in tritiated (170 mCi mmol^β1^) form by the highly stereospecific isotope exchange procedure involving penicillanic acid (R)βsulphoxide benzyl ester. The stereochemistry of the tritiation has been established by ^3^H n.m.r. in conjun
Neither intact nor regenerating planaria incorporated any significant amount of tritiated thymidine, tritiated L-leucine, or Ci4-L-leucine from free solution even over long periods of exposure. Tritiated thymidine was incorporated into regenerating rat liver and fed to planaria, but tritium hydrogen
## Abstract A new approach for the stereoselective synthesis of guanidineβderived amino acids, Lβarginine and (+)βblastidic acid, has been devised which allows the selective incorporation of isotopic labels in both the side chain of the amino acid as well as the guanidine unit. A new asymmetric syn
