Use for Nucleotide, Sugar Phosphate, Phospholipid, or Phosphoprotein Synthesis

Three papers have appeared this year disclosing new phosphoramidite reagents for the chemical 5 -phosphorylation of oligonucleotides. All three reagents,

Chiral ligands containing tervalent phosphorus acid derivatives as coordination sites continue to be explored for asymmetric metal catalysed reactions. New examples this year include the phosphite (119) and stereoisomers, the phosphites (120), 2 the diphosphinite TADDOP (121), the diphosphites (122) containing crown ethers, the aminophosphine-phosphinites AMPP s (123) and
