2H-Pyrido[3,2-B][1,4]Oxazin-3(4H)-One

Substitution Reactions: The oxazin-3-one ring can undergo substitution reactions, such as nucleophilic substitution, where a nucleophile can attack the carbonyl group. For example, you can perform nucleophilic acylation to replace the oxygen atom with another nucleophile. Reduction Reactions: The carbonyl group (C=O) can be reduced to form a hydroxyl group (C-OH) using reducing agents like sodium borohydride or lithium aluminum hydride. Cyclization Reactions: Depending on the reaction conditions, it's possible to perform intramolecular cyclization reactions to form other heterocyclic compounds. Condensation Reactions: You can perform condensation reactions to link this compound with other molecules or reagents to create larger compounds with extended conjugated systems. Oxidation Reactions: Depending on the specific substituents and reaction conditions, oxidation reactions can be applied to transform this compound into other products. Hydrolysis: Under appropriate conditions, you can perform hydrolysis reactions to cleave the oxazin-3-one ring and produce simpler compounds. Nucleophilic Addition: Nucleophiles can attack the carbon-carbon double bond in the pyrido ring or the oxazin ring, leading to various addition reactions.
