A chemical probe for the estrogen receptor: Synthesis of the 3H-isotopomer of raloxifene
Dodge,Stocksdale,Jones
, p. 43 - 49 (1995)
Radiolabelled raloxifene (LY156758) has been prepared by tritium gas hydrogenolysis of a 3-aroyl-bis-brominated precursor. The requisite halogenated intermediate was accessed by regioselective aroylation of benzothiophene 6 with the acid chloride of 3,5-dibromo-4-[2-(1-piperdinyl)ethoxy]benzoic acid (5). Selective deprotection of the aryl methyl ethers in the presence of the ethoxy side-chain followed by palladium catalyzed halogen-tritium exchange provided the target compound with a specific activity of 30.1 Ci/mmol.

A strategy for position-selective epoxidation of polyprenols

supporting information; experimental part, p. 8089 - 8093 (2009/02/01)
An effective strategy has been developed for the efficient site-selective epoxidation of poylolefinic isoprenoid alcohols, based on the use of an internal control element for intramolecular reaction. The approach is illustrated by application to a series of polyisoprenoid alcohols (polyprenols) at substrate concentration of 0.5 mM. With polyprenol substrates having the hydroxyl function at one terminus, the internal epoxidation can be directed at the double bond of the polyprenol, which is either four or five away from the terminal hydroxyprenyl subunit.
Synthesis of binucleating ligands of pyridylphenol
