A new method for the synthesis of diverse N-alkylation compounds was developed via an iron-catalyzed etheric Csp3-O cleavage with the C-N bond formation in the reaction of π-activated ethers with various nitrogen-based nucleophiles. In addition, the mechanism of this reaction was investigated. The Royal Society of Chemistry 2013.

Derivatives of hexestrol , a non-steroidal estrogen, bearing photochemically reactive functional groups or γ-emmitting radionuclides, are useful as affinity labeling agents for the estrogen receptor or as imaging agents for receptor positive breast tumors, respectively.We have developed convenient synthetic routes to two side chain functionalized and aromatic ring functionalized hexestrol derivatives, based on a direct benzylic coupling reaction mediated by allylsilanes or silyl ketene acetals. 1-Dehydrohexestrol and variousaromatic ring substituted 1-dehydrohexestrol derivatives can be prepared by coupling 3-(trimethylsilyl)-1-(4-methoxyphenyl)propene with various reactive benzylic derivatives, and pentestrol derivatives are prepared by the coupling of the silyl ketene acetal derivative of p-methoxyphenyl acetic ester with benzylic derivatives.The R*,S* (erythro) and R*,R* (threo) diastereomers formed in each case can be separated readily by chromatography and recrystallization.This silicon-mediated approach to functionalized hexestrol derivatives provides a convenient route to many compounds of interest as biochemical probes and receptor-based diagnostic reagents.
