- TASTE MODULATING ALDEHYDES
-
Aldehydes of formula (I) (X represents an alkyl or alkenyl group having up to 9 carbon atoms) for use in taste modulation and/or flavor compositions are provided. Specifically, the compounds of the presently disclosed subject matter provide effective and unexpected taste modulating properties. The taste modulation and/or flavor compositions can be incorporated into various consumer end products in particular in combination with high intensity sweeteners.

- Identification and Synthesis of New γ-Lactones from Tuberose Absolute (Polianthes tuberosa)
-
Six unsaturated γ-lactones, (Z)-5-octen-4-olide (1), (Z)-5-decen-4-olide (2), (Z)-6-nonen-4-olide (3), (Z)-6-dodecen-4-olide (4), (Z,Z)-6,9-dodecadien-4-olide (5), and tuberolide (6) have been identified for the first time in tuberose absolute (from Polianthes tuberosa L.).All structures were corroborated by synthesis and all, except 3 and 4, are new.An improved method for the stereoselective synthesis of (+/-)-cis-bicyclo-non-3-en-7-one (23) by an AlCl3-catalyzed Diels-Alder reaction is reported.
