1. Ring closure can be accomplished in the presence of thionyl chloride.2. Baldwin's rules discuss the relative rates of ring closures of these various types. 3. In conjunction with the Erding Ring Closure , trains would continue via Dorfen to Salzburg. 4. Alkenes with the interacting groups substituted cis to each other also assists in ring closure . 5. Aryl systems with the interacting groups substituted ortho to each other assists in ring closure . 6. It is produced from 1, 5-dibenzoylnaphthalene by oxidative ( dehydrogenative ) ring closure . 7. This is for snooping, ring closures ( see below ), and hot-plugging. 8. In aliphatic 4-and 5-oxocarboxylic acids, intervening substituents assists in ring closure . 9. The conditions under which these cyclization reactions occur follow Baldwin's rules for ring closure . 10. The resulting dialkoxides can then undergo amine displacement and ring closure at 25�C to form tropocoronands 4.
