Interpretation Introduction

Interpretation:

The most reasonable structure of naringenin chalcone is to be determined on the basis of the given hypothesis.

Concept Introduction:

In intramolecular Claisen condensation, a new five or six membered ring is formed.

An enolate acts as a nucleophile and a new carbon-carbon bond is formed between a carbonyl carbon and the enolate.

Other carbonyl groups, if present, remain intact.

They are converted to enol form if the enol form is more stable compared to the keto form.

Myo-inositol, the most prominent naturally occurring form of inositols, is a carbocyclic polyol that plays an important role as the structural basis for a number of secondary messengers in eukaryotic cells. It is generated in vivo from the aldol cyclization of glucose-6-phosphate to myo-inositol-1-phosphate

When the gum of the shrub Sterculia setigera is subjected to acidic hydrolysis, one of the water-soluble components of thehydrolysate is found to be tagatose. The following information is known about tagatose:(1) Molecular formula C6H12O6(2) Undergoes mutarotation.(3) Does not react with bromine water.(4) Reduces Tollens reagent to give d-galactonic acid and d-talonic acid.(5) Methylation of tagatose (using excess CH3 I and Ag2O) followed by acidic hydrolysis gives1,3,4,5-tetra-O-methyltagatose.(a) Draw a Fischer projection structure for the open-chain form of tagatose.(b) Draw the most stable conformation of the most stable cyclic hemiacetal form of tagatose
