Esters in which the alcohol part is sterically hindered around the ester bond, i.e. derived from tertiary alcohols are enzymatically prepared under low water conditions using Candida antarctica lipase A or a lipase species having a substrate activity similar to that of Candida antarctica lipase A with respect to tertiary alcohol esters.

[FR] L'invention concerne des esters dans lesquels la partie alcool est stériquement empêchée autour de la liaison ester, c'est-à-dire dérivée d'alcools tertiaires; ces esters sont préparés enzymatiquement dans un faible pourcentage d'eau à l'aide de la lipase A de Candida antartica ou d'une variété de lipase ayant une activité de substrat semblable à celle de la lipase A de Candida antartica en ce qui concerne les esters d'alcools tertiaires.
