title: Synthesis of 3-(12-hydroxy-p-carboranyl)propionic acid, a hydrophobic, N-terminal tyrosine-mimetic for peptides.
abstract: A new, p-carborane containing analog of tyrosine, namely 3-[1-hydroxy-1,12-dicarba-closo-dodecaboran(12)-12-yl]propionic acid was prepared from p-carborane in five steps involving hydroxypropylation of O-protected 1-hydroxy-p-carborane as the key transformation. The simple tyrosine mimetic can function as a hydrophobic surrogate for an N-terminal tyrosine residue in insect and mammalian neuropeptides to enhance the lipophilicity, and therefore, the cuticle and/or tissue permeability properties of mimetic analogs.
