Procedure

Scheme 1 illustrates an exemplary method for making a compound of the formula 1.3. Starting from (R)-5-methoxy-3-methyl-5-oxopentanoic acid, reaction with methyl chloroformate gives (R)-5-methoxy-4-(methoxycarbonyl)-3-methyl-5-oxopentanoic acid, which can be esterified with, for example, trimethylsilyl chloride and methanol to give compound 1.3, (R)-trimethyl 2-methylpropane-1,1,3-tricarboxylate.
