The difference in reactivity of (-)-mono and dimenthyl vs. diethyl alkylphosphonates in the α-lithiation reaction: Carbanionic synthesis of unknown (-)-dimenthyl 1-iodoalkylphosphonates and their first use in the radical iodine atom transfer addition (I-A

Unknown (-)-dimenthyl and ethyl (-)-menthyl 1-iodoethylphosphonates were synthesized via 1-lithio derivatives in 85-87% yields. Starting (-)-dimenthyl alkylphosphonates (R = Me, Et, i-Pr) were obtained in the Michaelis-Becker reaction (75-81% yields) and/

Stereochemically pure di(1R,2S,5R)-menthyl (S)- and (R)-2-hydroxy-3- chloropropylphosphonates were synthesized by reaction of di(1R,2S,5R)-menthyl ketophosphonate with chiral complexes prepared from sodium borohydride and (R,R)-(+)-tartaric acid or with (
