- Cembrene, C20H32, is a diterpenoid hydrocarbon isolated from pine resin. Cembrene has a UV absorption at 245 nm, but dihydrocembrene (C20H34), the product of hydrogenation with 1 equivalent of H2, has no UV absorption. On exhaustive hydrogenation, 4 equivalents of H2 react, and octahydrocembrene, C20H40, is produced. On ozonolysis of cembrene, followed by treatment of the ozonide with zinc, four carbonylcontaining products are obtained: Propose a structure for cembrene that is consistent with its formation from geranylgeranyl diphosphate.arrow_forwardis steric hinderance not an issue here? why when reacting with KOC(CH3)3 does it yield 2-isopropyl-1-pentene and it yields 2,3-dimethyl-2hexene here?arrow_forward(ii) Draw the product R, including a detailed reaction mechanism for the conjugate addition reaction between the 1,3-dicarbonyl P and the a,ß-unsaturated ketone Q.
