General description

1,1,3-Trichloroacetone is direct-acting mutagens in the Ames/Salmonella assay. It is precursor for the generation of 1,3-dihalo oxyallyl intermediates, which undergo [4 + 3] cycloadditions with a host of 1,3-diene systems.

Application

1,1,3-Trichloroacetone was used in base-induced solvolyses of [3.2.1]Bicyclic α,α′-dichloro ketones.

Polycomb repressive complex 1 (PRC1) plays essential roles in cell fate decisions and development. However, its role in cancer is less well understood. Here, we show that RNF2, encoding RING1B, and canonical PRC1 (cPRC1) genes are overexpressed in breast cancer.
