1. These reactions are both ring opening reactions and cleavage reactions. 2. In this ring opening reaction, there is an issue of torquoselectivity. 3. Consequent lactam-ring opening and functionalization were expected to give Taxol. 4. Most biodegradable polymers are synthesized by ring opening polymerization. 5. Certain barrelenes have been used as a monomer in a ring opening metathesis polymerization: 6. He has also synthesised catenanes and metal-containing polymers by dynamic ring opening polymerisation. 7. But the epoxide product itself is vulnerable to ring opening , isn't it? 8. Recently, a certain type of spiropyran was reported, which shows glutathione induced ring opening . 9. For example, they can polymerize olefins, and participate in ring opening polymerizations, etc. 10. To close the fructose ring, the reverse of ring opening occurs and the ketose is protonated.
