Diels-Alder Reaction: Synthesis of cis-Norbornene-5‚ 6-endo-dicarboxylic anhydride Introduction: The Diels-Alder reaction is a [4+2] cycloaddition of a conjugated diene and a dienophile. This type of reaction was named for Otto Diels and Kurt Alder who were the first to investigate this reaction (Weldegirma‚ 2012). The Diels- Alder reaction is one of the most important reactions in all of organic chemistry because of the applicability of it. This reaction can form new

The goal of this experiment was to synthesize dibenzalacetone by aldol synthesis. The name ’Aldol synthesis’ was taken from the words ’aldehyde and alcohol’. This is because the product of this reaction contains both an aldehyde and alcohol. The carbon-carbon bond-forming reaction is referred to as aldol addition. An aldol condensation yields many species of products if the reactant is more than one. Therefore‚ the aldehyde has to react with itself to yield one product. Procedure: Followed according

DNA synthesis inhibitors Nucleic acid inhibitors are chemicals which inhibit the production of nucleic acids including both DNA and RNA. DNA and RNA inhibitors inhibit enzyme action in DNA replication in the same way as the topoisomerase inhibitors we discussed earlier. Topoisomerase inhibitors (1) (10) are chemicals which interfere with the enzymes that allow DNA strands to separate and to re-join‚ a process that is required for the division of bacteria and without which DNA cannot effectively
