• Acid-catalysed esterifications that are commonly used can cause extensive dehydration or lactonization of hydroxy acids. Use of diazomethane, on the other hand, is not suitable for such preparations, because of its toxicity and hazard. Alternatively, the carboxyl groups are converted into monosilver salts which are then reacted with appropiate alkyl halides
