The following selectivities are reported for partitioning of the α- (N,N-dimethylthiocarbamoyl)-4-methoxybenzyl carbocation 1+ between nucleophilic addition of π-nucleophiles and a solvent of 50:50 (v:v) acetonitrile/water at 25 °C (nucleophile, k(Nu)/k(s)): pyrrole, 23 M-1; 2- methoxythiophene, ?2 M-1. No nucleophile adducts (+, and they provide support for a simple relationship between the Ritchie N+ scale of nucleophilicity in water and the Mayr N scale of nucleophilicity in weakly polar nonnucleophilic solvents. Our data require a large effective molarity for the intramolecular addition of a trisubstituted alkene to an allylic carbocation.

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.
