A series of novel silicon(IV) phthalocyanines conjugated axially with different nucleoside moieties (uridine, 5-methyluridine, cytidine, and 5-N-cytidine derivatives) have been synthesized and evaluated for their photodynamic activities. The uridine-containing compound 1 exhibits the highest photocytotoxicity against HepG2 human hepatocarcinoma cells with an IC50 value as low as 6 nM, which can be attributed to its high cellular uptake and non-aggregated nature in the biological media. This compound shows high affinity toward the mitochondria of HepG2 cells and causes cell death mainly through apoptosis upon illumination. The result indicates that 1 is a highly promising photosensitizer for photodynamic therapy.
direct method for the phosphorylation of alcohols, phenols, saccharides and nucleosides using triallyl phosphite is described. From primary or secondary alcohols, the corresponding diallyl-protected phosphorylated compounds are obtained in good to high yields. The method was found to be selective for primaryalcohols and to be applicable to diverse simple and functionalized alcohols, including amino acids

are associated with difficulty in purification of the by-products. To overcome these challenges, here, we report a simple route toward the diverse conversion of alcohols via an SN2 pathway, in which blue light-promoted iodination is used to form alkyl iodide intermediates from simple unreactive alcohols. The scope of the process tolerates a range of nucleophiles to construct C-N, C-O, C-S, and C-C
