derivatives of trivalent organophosphorus acids, containing PH and POSiMe3 fragments with various bis- and tris(alkoxymethyl)amines and bis(alkoxymethyl)amino acids, is proposed as a convenient method for the synthesis of new bis- and trisphosphorylated amines and amino acids as well as their derivatives with four and five coordinated phosphorus. Also the three-components systems of phosphorous acid, paraformaldehyde
Disclosed are substituted pyrimidines useful as HIF prolyl hydroxylase inhibitors to treat anemia and like conditions.

Novel and efficient Mn(OAc)3⋅2H2O promoted radical addition-[4 + 1] cyclization relay of 3-indolymethanols and phosphites was disclosed, which afforded 1,2-oxaphospholoindole derivatives in moderate to good yields. Based on the experimental and computational studies, a mechanism involving radical addition and intramolecular cyclization cascade was proposed.
