The synthesis of a given molecule via aldol reaction is to be shown. Concept introduction: Every aldol addition produces a β-hydroxycarbonyl compound. A new C-C bond is formed via aldol addition. When an aldehyde is treated with a strong base, NaOH which produced β-hydroxycarbonyl compound. The carbonyl and the hydroxyl groups in the product are separated by two carbon atoms. It is a nucleophilic addition reaction, where the starting compound aldehyde required α hydrogen. The new C-C bond which is formed in α-hydroxy carbonyl the compound can be a disconnect to get two carbonyl precursors. And these aldehyde precursors can undergo an aldol addition to produce a target molecule.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

How do I explain this? Thank you!

When an unknown amine reacts with an unknown acid chloride, an amide with a molecular mass of 163 g/mol (M* = 163 m/z) is formed. In the infrared spectrum, important absorptions appear at 1661, 750 and 690 cm. The 13C NMR and DEPT spectra are provided. Draw the structure of the product as the resonance contributor lacking any formal charges. 13C NMR DEPT 90 200 160 120 80 40 0 200 160 120 80 40 0 DEPT 135 T 200 160 120 80 40 0 Draw the unknown amide.
