Catalytic asymmetric synthesis of cyclopropylphosphonates - Catalysts' scope and reactivity

Article abstract of DOI:10.1139/v05-074

The transition metal-catalyzed cyclopropanation of alkenes using α-diazomethylphosphonates leads to cyclopropylphosphonate derivatives in high yields. The reaction proceeds well with copper, rhodium, and ruthenium catalysts. The best catalysts for the ena
