The present invention provides indole derivatives of the general formula: ##STR1## The indole derivatives of the invention have potent antiestrogen activity and are useful as drugs for the treatment of estrogen-dependent diseases, such as anovulatory infertility, prostatic hypertrophy, osteoporosis, breast cancer, endometrial cancer and melanoma.
An indole derivative represented by general formula (1). It has a potent antiestrogenic effect and hence is useful for treating estrogen-dependent diseases such as anovular infertility, prostatomegaly, osteoporosis, breast cancer, endometrial cancer and melanoma.
An efficient cross-coupling of aryl bromides with sodium sulfinates, using an organoboron photocatalyst with nickel, is described herein. Under the irradiation of white light, this dually catalytic system enables the synthesis of a series of sulfone compounds in moderate to good yields. A broad range of functional groups and heteroaromatic compounds is tolerated under these reaction conditions. The
