This material widens the range of use to include flavors that heptan-2-one, for example, would struggle to adapt to.

Cycloheptadecanone from Dimethyl Octadecanedioate via a One-Step Catalytic Process

Although the reaction was not studied, it does establish that a one-step conversion of the long chain diesters to the cyclic ketone containing one less carbon atom can occur. It opens the possibility to simpler processes for the preparation of macrocyclic ketones.

1-(2-Furfurylthio) Propanone

From Symrise, this material has a distinctly rich coffee odor.

Analysis of Glycosidically Bound 2,5-Dimethyl-4-hydroxy-3 (2H)-furanone in Pineapple

This paper reports evidence of the presence of glycosidically bound DMHF in pineapple. In the last few years the analysis of flavor precursors and intermediates, especially glycosides in fruits, has received increasing interest and attention (Strauss, et al., 1986; Schwab and Schreier, 1988).
