Estrone sulfonates as inhibitors of estrone sulfatase
Howarth, Nicola M.,Purohit, Atul,Reed, Michael J.,Potter, Barry V. L.
, p. 346 - 350 (1997)
In our continuing quest to design efficient inhibitors of estrone sulfatase activity and to assess the recognition of estrone sulfate surrogates by estrone sulfatase, we synthesized and evaluated several sulfonate derivatives of 5,6,7,8-tetrahydronaphth-2
Photochemical Behavior of Some Estrone Aryl and Methyl Sulfonates in Solution: Preparative and Mechanistic Studies
Quindt, Matías I.,Gola, Gabriel F.,Ramirez, Javier A.,Bonesi, Sergio M.
, p. 8 - 21 (2020/06/03)
Direct irradiation of estrone aryl and methyl sulfonates in different organic solvents under nitrogen atmosphere was investigated under steady-state conditions. The estrone derivatives reacted efficiently through the photo-Fries rearrangement reaction involving [1;3]-sulfonyl migration providing the ortho-sulfonyl estrone derivatives and estrone as the photoproducts. In addition, estrone and 2-arylsulfonyl estrone derivatives were epimerized involving a Norrish Type-I reaction. Chemical quenching and photosensitization experiments on the photoreaction have been also carried out to establish the photoreactive excited state. Likewise, the solvent effect and the nature of the sulfonyl group on the photoreactions have been also studied.

This work describes the cross-electrophile methylation of aryl bromides and aryl tosylates with methyl tosylate. The mild reaction conditions allow effective methylation of a wide set of heteroaryl electrophiles and dimethylation of dibromoarenes.
Facile Deoxygenation of Phenols and Enols Using Sodium Borohydride-Nickel Chloride
Wang, Feng,Chiba, Kazuhiro,Tada, Masahiro
, p. 1897 - 1900 (2007/10/02)
A facile deoxygenation reaction of phenol and 1,3-dicarbonyl compounds was investigated.Phenols, enolizable 1,3-diketones and 3-ketoesters were converted into the toluene-p-sulfonates which were reduced by a sodium borohydride-nickel chloride system to give the deoxygenated aromatic compounds, alcohols and esters, respectively.
