β-Substituted β-amino acids, β-substituted β-amino acid derivatives, and β-substituted β-amino acid analogs and (bio)isosteres and their use as chemotherapeutic agents are disclosed. The β-substituted β-amino acid derivatives and β-substituted β-amino acid analogs and (bio)isosteres are selective LAT1/4F2hc substrates and exhibit rapid uptake and retention in tumors expressing the LAT1/4F2hc transporter. Methods of synthesizing the β-substituted β-amino acid derivatives and β-substituted β-amino acid analogs and methods of using the compounds for treating cancer are also disclosed. The β-substituted β-amino acid derivatives and β-substituted β-amino acid analogs exhibit selective uptake in tumor cells expressing the LAT1/4F2hc transporter and accumulate in cancerous cells when administered to a subject in vivo. The β-substituted β-amino acid derivatives and β-substituted β-amino acid analogs and (bio)isosteres exhibit cytotoxicity toward several tumor types.

iodide or bromide to catalyze the ethoxylation of alcohols and phenols, giving good rates and narrow product distributions. The combined action of a weak electrophile [B(OR)3] and a weaknucleophile (halide) allows for the ethoxylation of base‐sensitive alcohols. Experiment suggests a new mechanism for this commercially important reaction proceeding through key β‐haloalkoxy intermediates.

conserved signal molecules that mediate quorum sensing in Gram-negative bacteria. In this study, deuterium-labeled AHLs were prepared for use as internalstandards for isotope dilution mass spectrometry. Their utility in the sensitive and precise quantification of AHLs in culture supernatants of bacteria by GC/MS was demonstrated.
