M. Murakata et al., ENANTIOSELECTIVE RADICAL-MEDIATED REDUCTION OF ALPHA-IODOLACTONE USING TRIBUTYLTIN HYDRIDE IN THE PRESENCE OF A CHIRAL AMINE AND A LEWIS-ACID, Journal of the Chemical Society, Chemical Communications, (4), 1995, pp. 481-482
Enantioselective radical-mediated reduction of alpha-methoxymethyl-alp
ha-iododihydrocoumarin 1 using tributyltin hydride is realized in up t
o 62% enantiomeric excess (e,e.) (88% chemical yield) by combination o
f chiral diamine 2 and magnesium iodide.
