A straightforward procedure ensuring the anchoring of bisphosphonate moiety into alcohols or phenols is described. The method uses a bisphosphonate-metal-carbenoid O-H insertion reaction for which copper(II) triflate was found to be an efficient catalyst.

Some current and potential therapeutic uses of bisphosphonates and phosphonocarboxylates are summarized. The feasibility of synthesizing α-hydroxy α-alkyl/aryl methyl-enebisphos-phonates via Grignard addition to tetraalkyl carbonylbisphosphonates 6 is demonstrated, and a new synthesis of 6 under very mild conditions is described.
inhibitors of the phosphorolytic activity of native and drug-resistant forms of HIV-1 reverse transcriptase (RT) was performed. It was shown that with the increase of the inhibitory potential of BPs towards the phosphorolytic activity raises their ability to inhibit the RT-catalyzed DNA elongation. Herein, we report the impact of the thymidine analog mutations (TAM) on the activity of bisphosphonates, as well

The synthesis and rhodium mediated O-H insertion reactions of a wide range of diazo compounds are described. The rate at which the diazo compounds decompose in the presence of 2-propanol and the rhodium catalyst is strongly dependent on the electron withdrawing group(s) attached to the diazo carbon, with diazophosphonates being the least reactive.
