Estrogen receptor ligands. Part 3: The SAR of dihydrobenzoxathiin SERMs
摘要:
A series of 3-alkyl, 3-cycloalkyl, and 3-heteroaryl dihydrobenzoxathim analogs 1 were prepared and evaluated for estrogen/anti-estrogen activity in both in vitro and in vivo models. In general, the compounds were found to exhibit a high degree of selectivity for ERalpha over ERbeta, but were less potent than the original lead compound la in the inhibition of estradiol-driven uterine proliferation.

[GRAPHICS]TFA/Et3SIH-mediated cyclization of thioketones 5 derived from the reaction of functionalized thiophenols (catechols) with bromo ketones gave syn 2,3-bisaryl(or heteroaryl) dihydrobenzoxathiins and benzodioxane 1 with total diastereoselectivity (>99:1), in excellent yields.
