New reagent system for attaining high regio- and stereoselectivities in allylic displacement of 4-cyclopentene-1,3-diol monoacetate with aryl- and alkenylmagnesium bromides.
Org. Lett. 7(2) , 183-6, (2005) [Reaction: see text] Low regioselectivity of RMgBr (R = aryl, alkenyl) in the CuCN-catalyzed reaction with 4-cyclopentene-1,3-diol monoacetate is improved by addition of LiCl or MgCl2 to a similar extent as previously obtained with RMgCl (>90:10). The limitat... |

Preparation of ethyl magnesium bromide for regiospecific analysis of triacylglycerols.
J. Oleo Sci. 57(8) , 459-62, (2008) This paper presents a procedure for preparation of a Grignard reagent, ethyl magnesium bromide, used for partial deacylation of triacylglycerols (TAG) in their regiospecific analysis. Magnesium turnings were reacted with ethereal solution of bromoethane in a ... |
