Abstract:
1. A method of making compounds of Formula 9, or Formula 10, or opposite enantiomers thereof, wherein R is C X is C the method comprising epimerizing compounds of Formula 7, or Formula 8, or opposite enantiomers thereof, said epimerizing compounds of compounds of formula 7 or formula 8 at a temperature greater than or about equal to 100° C. and less than or about equal to the decomposition temperature of the compounds of Formula 7 or Formula 8, to give the compounds of Formula 9, or Formula 10, or the opposite enantiomers thereof, respectively, wherein R and X in Formula 7 and Formula 8 are as defined in Formula 9 and Formula 10.
