- New catalyst for phosphonylation of C=X electrophiles
-
Pyridinium perchlorate is found to be an efficient and recyclable catalyst for the reaction of trialkyl phosphites with various C=X electrophiles (aldehydes, ketones, ketophosphonates, imines, isocyanates, isothiocyanates, activated alkenes) to afford cor

- Synthesis of α-hydroxy(polyprenyl) bisphosphonates
-
Bisphosphonates derived from natural terpenes were synthesized by phosphonylation of corresponding aldehydes. The general strategy of introduction of the phosphonate groups into the polyprenol molecule involves successive treatment of a hydroxyl compound by Swern reagent to oxidize the C-OH group into C=O and a (EtO)3P/[PyH]+ClO - 4 mixture to phosphylate the resulting carbonyl compound.
