A new double coupling system: synthesis of citronellyl acetate via transacetylation to citronellol from acetyl coenzyme A produced from glucose and free fatty acids.

A double coupling system, which couples metabolism of glucose and transacetylation, is a unique procedure for the production of acetic esters. In the novel coupling system described in this article, acetyl coenzyme A (acetyl-CoA) was supplied via metabolism of both glucose and exogenous saturated fatty acids. While short and middle chain fatty acids having C4-8 were very biotoxic, myristic acid (C14) was effectively used as a source of acetyl-CoA.
