Abstract:
Sulfoximine-based acyclic triaryl olefins 8 and 9 have been prepared and initial studies have been performed to determine their biological profiles. In contrast to their sulfonyl-substituted analog 2 sulfoximines 8 and 9 show low COX inhibitory activity. All compounds affect the estrogen receptors. While sulfone 2 interacts exclusively with ER β, sulfoximines 8 and 9 reveal almost equal blocking potencies for both estrogen receptors, ER α and ER β. In the tested series, triaryl olefin 9a shows the highest inhibitory activities with 91% and 80%, respectively (at 10 μM).

Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy acids to...
