The present invention relates to a method for preparing α-hydroxy, α-substituted methylenebisphosphonates and phosphonoacetates via addition of Grignard or organoindium reagents to tetraalkyl carbonylbisphosphonates and trialkyl carbonylphosphonoacetates. Also disclosed are compounds so synthesized.
Novel phosphonate compounds are provided including a phosphonoglyoxylamide ester, an &agr;-keto phosphonophosphinate ester, a carbonylbisphosphonate analog of a nucleotide, and a diazomethylenebisphosphonate analog of a nucleotide, as well as methods of making synthetically and medically useful &agr;-keto phosphonate compounds.
