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.

An electrondonor–acceptor (EDA) complex photoactivation strategy for radicalfluorosulfonylation is disclosed for the first time. Simply upon blue light irradiation, the FSO2 radical can be generated efficiently under catalyst-free, base-free, and additive-free conditions, which enables facile access to 6-keto alkenylsulfonyl fluorides from readily available propargyl alcohols and FSO2Cl. The 6-keto
(EN) Compounds of formula (I), wherein R1 is hydroxy or C1-10alkyl, and $i(in vivo) hydrolysable esters and salts thereof are described as agents for the treatment of obesity and related conditions. Processes for their preparation and intermediates are described.(FR) Les composés de la formule (I), où R1 est de l'hydroxy ou un alcoyle C1-10, et des esters pouvant être hydrolysés $i(in vivo) et des sels de ceux-ci, sont décrits à titre d'agents pour le traitement de l'obésité et des conditions apparentées. On décrit également des procédés de préparation desdits composés, ainsi que les produits intermédiaires.
