The present invention is for sanitizing compositions for sanitizing surfaces which may contact food. The composition may be provided in liquid form, and may include a quaternary amine, one or more surfactant, a fragrance, and water. At least 90% by weight of the fragrance comprises fragrance components that meet Class I qualifications of the Cramer classification system. All other components of the composition (e.g., the quaternary amine, the surfactants, water, and any optional components) meet the EPA guidelines under CFR 180.940(a). Since the composition only includes components that meet the EPA guidelines under CFR 180.940(a) (reflecting a presumption of low toxicity), and at least 90% of the fragrance itself (e.g., in the case of mixtures of fragrance components) meets the Cramer Class I qualifications, the composition is safe for application to surfaces that come in contact with food, where there is a heightened probability that traces of the composition will be ingested.

water-accelerated catalytic carboalumination, a Claisen rearrangement, and a nucleophilic carbonyl addition converts terminal alkynes and allyl vinyl ethers into allylic alcohols containing up to three contiguous asymmetric carbon centers. Stoichiometric quantities of water as an additive increase the rate of the [3,3] sigmatropicrearrangement as well as the diastereoselectivity of the carbonyl addition
