Compounds with unique liphagane meroterpenoid scaffold having boronic acid functionality in the skeleton are described (formula 1) together with pharmacological potential of these compounds as anticancer agents. A method of preparation and inhibiting the activity of phosphoinositide-3-kinase (PI3K-alpha and beta) has been presented. In particular, the invention describes a method of inhibiting PI3K isoforms, wherein the compounds are novel structures based on liphagane scaffold with unique boronic acid functionality. The methods and uses thereof are described herein this invention.

originally occupied by the bromine. Formation of pentafluoroethyl compounds is explained by decomposition of trifluoromethylcopper to cuprous fluoride and difluorocarbene, which can then react with a further molecule of trifluoromethylcopper to form pentafluoroethylcopper. This then reacts with aryl halide to give pentafluoroethyl compounds. Perfluoroalkylcopper is thermally cleaved to perfluoroalkyl radical
