A novel and direct synthesis of various 2-aminobenzo[b]thiophenes has been developed. The reactions were catalyzed by a combination of Pd(dppf)Cl2 and dppf using odorless and cheap Na2S2O3 as the sulfur source. This strategy allowed us to synthesize important 2-aminobenzo[b]thiophene scaffold more efficiently and conveniently.

Three fluoroalkylated derivatives (1-3) of the selective estrogen receptor modulator (SERM), raloxifene, have been synthesized. The key step in the synthesis is the C-C bond formation of benzo[b]thiophene and a substituted phenyl group (ring C) using a Stille reaction. The in vitro binding affinities of the substituted raloxifenes 1-3 are 45, 60, 89%, respectively, relative to the affinity of estradiol, which is higher than the affinity of raloxifene itself (25%). When labeled with the positron-emitting radionuclide, these compounds might be useful as PET imaging agents for estrogen receptor-positive breast tumors.

This invention provides a series of substituted benzo[b]thiophenes useful in reversing multidrug resistance in a resistant neoplasm. The present invention also provides methods for reversing the multidrug resistance in a resistant neoplasm by treating a mammal in need of said treatment with a substituted benzothiophene. This invention also provides methods for treating neoplasms in a mammal which comprises administering to a mammal in need of this treatment a substituted benzothiophene in combination with an oncolytic agent.
