Hydroxylated or glycosylate unsatd. derivs. of spiro vetivone - as aromatising agents for tobacco

摘要

New concentrated substances (A) comprises a mono- or disubstd., hydroxy or glycosyloxy deriv. (I) of spirovetivvone. Also claimed are smoking materials based on tobacco (substitutes) and contg. 0.01-2 wt. % of (A) as aromatising agent. Pref. cpds. (I) are formulae (Ia) and (Ib) (where one of R1 and R2 is H and the other is OH or glycosyloxy derived from a mono- or disaccharide; the dotted lines represent the possible posns for an optional double bond; R3 is OH or glycosyloxy as for R1- 2). The glycosyloxy gp. is pref. derived from beta-d-glu 2). The glycosyloxy gp. is pref. derived from beta-d-glucose.
