A method for the preparation of benzene derivatives from myo-inositol, an abundantly available phyto chemical is described. 1,3-Bridged acetals of inososes undergo step-wise elimination leading to the formation of polyoxygenated benzene derivatives. This aromatization reaction proceeds through the intermediacy of a β-alkoxyenone, which could be isolated. This sequence of reactions starting from myo-inositol

The chemistry and biology of phosphorylated inositols have become intense areas of research during the last two decades due to their involvement in various cellular signaling processes. However, the metabolic instability by phosphatases or kinases and poor penetration make it difficult to become a drug used in the clinic. The bioreversible protection technique can enhance membrane penetration characteristics and increase the stability of phosphorylated inositols against enzymatic degradation and is applied widely in drug discovery and development. In this paper, we described the design and synthesis of 22 bioreversible phosphotriester inositols, along with the initial antitumor activity results. Most compounds exhibited significant cytotoxic activity against human cancer cell lines A549, MDA-MB-231 and HeLa, but lower cellular toxicity on normal cell MCF10A in comparison with Cisplatin. These compounds can be used as probes to study the mechanism of intracellular signal transduction mediated by phosphate inositol or as leads of phosphate inositol drugs in the clinic.
