IDENTIFICATION AND USE: Jasmone is a pale yellow, viscous liquid (oil). It is used in perfumery in fine jasmin bases and floral compositions. HUMAN EXPOSURE AND TOXICITY: Jasmone did not induce dermal sensitization in human volunteers. ANIMAL STUDIES: In an acute dermal toxicity study in 10 rabbits were give 5 g/kg cis-jasmone and observed for 14 days. Severe redness was seen in nine animals and moderate edema was observed in all animals. Eschar was found in two rabbits. Jasmone was not irritating or sensitizing in guinea pigs. In a rabbit eye irritation study, the highest dose group showed strong redness, strong secretion and edema, completely resolving by day 6. The remaining doses showed slight to moderate redness and secretion, completely resolving by day 3. Jasmone was not mutagenic in the Ames plate incorporation and pre-incubation assays with and without metabolic activation at concentrations up to 2500 ug/plate. The strains of Salmonella typhimurium used in the assays were TA98, TA100, TA102, TA1535 and TA1537. However, in a cytogenetic assay in Chinese hamster ovary (CHO) cells frequency of sister-chromatid exchanges (SECs) was significantly increased at concentrations of 33.3 uM and at 100 and 300 uM, the highest dose tested.
/SRP:/ Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Poisons A and B/
/SRP:/ Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary.

/HUMAN EXPOSURE STUDIES/ Repeated insult patch tests were conducted to determine if cis-jasmone would induce dermal sensitization in human volunteers. During the induction phase, 0.5 mL of 2% cis-jasmone in dimethyl phthalate was applied onto an occlusive patch and applied to the upper arm of each volunteer for 24 hr. Induction applications were made to the same site on Monday, Wednesday and Friday for a total of 9 applications during a 3-week period. Following a two week rest period, a challenge patch was applied to a site previously unexposed. Patches were applied as in the induction phase and kept in place for 24 hr before removal. Reactions to the challenge were scored at 48, and 72 hr after application. None of the 54 subjects tested experienced any sensitization reactions.

to be resolved in the design of iron catalysts for olefin syn-dihydroxylation with potential utility in organic synthesis. Toward this end, in this work a novel catalyst bearing a sterically encumbered tetradentate ligand based in the tpa (tpa = tris(2-methylpyridyl)amine) scaffold, [FeII(CF3SO3)2(5-tips3tpa)], 1 has been designed. The steric demand of the ligand was envisioned as a key element to support

calcium-mediated regioselective 1,2-reduction of challenging α,β-unsaturated ketones, such as 2-cyclopententone, is reported. The corresponding allylic alcohols are obtained in very good regioselectivities using Ca(OTf)2 and NaBH4. Furthermore, we have shown that our method can stereoselectively reduce aziridinyl ketones.
A highly regioselective nickel-based catalyst system for the isomerization/hydrocyanation of aliphatic internal olefins is described. This benign tandem reaction provides facile access to a wide variety of aliphatic nitriles in good yields with excellent regioselectivities. Thanks to Lewis acid-free conditions, the protocol features board functional groups tolerance, including secondary amine and unprotected

N-sulfonylhydrazones of cyclic ketones are readily transformed into NH-free spirocyclic pyrrolidines and isoindolines by reaction with γ-azidoboronic acids. The transition-metal-free transformation is widely applicable and represents a new disconnection towards spirocyclic pyrrolidines. The application of the reaction in the modification of natural steroids and other biorelevant molecules highlights

The synthesis of jasmone and related jasmonoids and pyrethroids is described. These compounds play a defensive role in plants and share a common cyclopentenone core with variations in the side chains. Jasmone, cinerone, allylrethrone, and derivatives were synthesized through π-allyl palladium cross-coupling of stannane derivatives. With selective hydrogenation, dihydrojasmone, and dihydrocinerone were
