A (Z)-solanone has the steric formula of: or with the name of (S,Z)-5-isopropyl-8-methyl-6,8-diene-2-one or (R,Z)-5-isopropyl-8-methyl-6,8-diene-2-one. A process for the preparation of the (Z)-type solanone and the use thereof in flavoring of cigarette shred are further disclosed. The process includes the following steps: (1) reacting isopentanal and methyl vinyl ketone, under the action of a catalyst and a co-catalyst, to give (S)-2-isopropyl-5-carbonylhexanal or (R)-2-isopropyl-5-carbonylhexanal; (2) reacting the (S)-2-isopropyl-5-carbonylhexanal or the (R)-2-isopropyl-5-carbonylhexanal obtained in step (1) with (iodomethyl)triphenylphosphonium iodide, to give (S,Z)-7-iodo-5-isopropyl-6-ene-2-one or (R,Z)-7-iodo-5-isopropyl-6-ene-2-one; and (3) reacting the (S,Z)-7-iodo-5-isopropyl-6-ene-2-one or the (R,Z)-7-iodo-5-isopropyl-6-ene-2-one obtained in step (2) with pinacol isopropenylborate in the presence of a catalyst to give the (Z)-solanone.

(z)-solanone, and preparation process and use thereof

An electronic cigarette liquid supply device includes the piezoelectric substrate, the insulating film, the first interdigital transducer, the second interdigital transducer, the liquid storage chamber, the flow channel and the liquid outlet. A liquid inlet is provided on the liquid storage chamber. One end of the flow channel is hermetically connected to the liquid storage chamber, and the other end of the flow channel is the liquid outlet. The first interdigital transducer and the second interdigital transducer are attached to a surface of the piezoelectric substrate and located between the piezoelectric substrate and the insulating film. The liquid storage chamber, the flow channel and the liquid outlet are provided outside and above the insulating film.
