Significance

The tamoxifen homologue G displays high antiestrogenic potency in antiproliferative assays against MCF-7 breast cancer cells (M. J. Meegan et al. J. Med. Chem. 2001, 44, 1072). The tetrasubstituted alkenylboronate E used in the synthesis was derived by lithiation of the organodiboronate C with lithium tetramethyl­piperidide (LiTMP) followed by nucleophilic addition of the organolithium intermediate D to propio­phenone.
