Jewellyn G. Diola; ladyjewellyndiola@yahoo.com Abstract Synthesis of 3‚4-dihydro-3-(p-methylphenyl)-1‚2-(2h)-benzoxazine involves the nucleophillic addition of the 1 °amine group upon the carbonyly group of the salicylaldehyde‚ the reduction of imine to amine and the addition of paraformaldehyde to proceed ring closure. The experiment prepared the product through Mannich reaction‚ a multicomponent condensation synthesis between ketone‚ aldehydes‚ enols and amines. Biosynthesis of benzoaxazines

Chapter 16: Capital Structure: Basic Concepts 16.1 a. Since Alpha Corporation is an all-equity firm‚ its value is equal to the market value of its outstanding shares. Alpha has 5‚000 shares of common stock outstanding‚ worth $20 per share. Therefore‚ the value of Alpha Corporation is $100‚000 (= 5‚000 shares * $20 per share). b. Modigliani-Miller Proposition I states that in the absence of taxes‚ the value of a levered firm equals the value of an otherwise identical unlevered

Introduction Cinnamaldehyde‚ cinnamic aldehyde or 3-phenyl-2-propenal is the major constituent of cinnamon oil‚ extracted from several species of Cinnamomum (C. verum‚ C. burmanii‚ C. cassia)‚ under the family Lauraceae‚ a group of evergreen trees. Cinnamon bark (particularly C. verum) yields 0.4-0.8% oil‚ which contains 60-80% cinnamaldehyde

Name Period Date The Synthesis of Aspirin Background Pharmaceutical research labs perform chemical reactions between organic molecules that contain mostly carbon. Since the atoms in organic molecules tend to be nonmetals‚ then the bonds that hold them together are covalent bonds. Only a few elements on the periodic table are nonmetals: C‚ N‚ O‚ S‚ Cl‚ and F. This small number of elements can be bonded together in different quantities‚ bonding types (single‚ double‚ triple bonds)‚ and structural
