Several functionalized diolefins cyclize to hydroazulenes (among others) via olefin metathesis with CH3ReO3. These conversions are regioselective and occur with high diastereoselectivity.
six-membered hemiacetal, a seven-membered oxazepane, and a dimethylpyrrolecarboxy group. By a novel and simple convergent strategy involving Pd/Ag-promoted Suzuki–Miyaura coupling and Dieckmann condensation reactions, the totalsynthesis of batrachotoxin was realized in 22 steps.
A method of using organic compounds and providing slow release flavoring in or for food products wherein flavor precursors are added to flavor compositions and/or food products and release flavor compounds upon consumption of the food products, and novel flavor precursor compounds. The flavor precursors can be prepared from monoglycerides and flavor compounds which comprise one or more carbonyl groups.
