Abstract

Abstract Described are α-oxy(oxo) sulfides and ethers having the generic structure: ##STR1## wherein X is one of: ##STR2## Z is one of sulfur or oxygen; when R 1 and R 2 are taken separately, R 1 is hydrogen or methyl, and R 2 is methyl; and when R 1 and R 2 are taken together, R 1 and R 2 form phenyl moieties; and Y is one of C 1 -C 4 alkyl, C 3 or C 4 alkenyl, acetyl, methoxycarbonylmethyl, or 1,3-diethylacetonyl. Addition of one or more α-oxy(oxo) sulfides and ethers to foodstuff flavorings or foodstuffs is indicated to produce the following aroma and flavor characteristics, in the alternative or taken together: Aroma Green/spicey, Sweet, Fruity, Fresh/fruity, Gooseberry, Concord grape, Grape, Almond, Nutty, Cereal-like, Lachrymatory onion-like, Oniony, Green onion-like, Leek, Broccoli-like, Grapefruit, Celery stalk-like, Floral, Rosey, Woody, Blackcurrant, Buchu leaf oil-like, Citronellal-like, Neroli-like, Bergamot-like, Violet leaves-like, Jasmin-like, Melony, Cucumber-like, Green, Vegetable, Sweet/floral. Flavor Spicey, Sweet, Fruity, Milk caramel-like (dulce de leche-like), Gooseberry, Broccoli-like, Nutty, Cereal-like, Oniony, Grape, Concord grape, Citrusy, Grapefruit-like, Green fruit-like, Mandarin-like, Petitgrain-like, Blackcurrant, Minty, Astringent, Coriander-like, Green, Piney, Citronellal-like, Violet leaves-like, Melony, Green fruit-like, Cucumber, Green, Floral, Floral/green, Vegetable, Garlic With lasting mouthfeel and with, in many cases, an oniony aftertaste. The compounds of our invention are useful in augmenting or enhancing the flavor and aroma nuances of berry flavors, cereal-like flavors, nut flavors, broccoli flavors, onion flavors, citrus flavors (including neroli, bergamot, lime), jasmin flavors, grapefruit flavors, concord grape flavors, blackcurrant flavors, milk caramel flavors (e.g., dulce de leche-like flavors), vegetable flavors, cucumber flavors, celery flavors and spice flavors. Addition of a number of these α-oxy(oxo) sulfides and ethers in perfumes, colognes or perfumed articles imparts thereto sweet, green, floral, herbal, vegetative, basil-like, minty, melony, grapefruit, fruity and alliaceous aromas with yara, neroli and/or verdima-like nuances.
