The mechanism thataccounts for each step of the given synthesis is to be written. Concept introduction: Cyperone derives its name from the Cyperusrotundus, a nut grass found in tropical, subtropical and temperate regions. It can exist in both α − and β − forms. It is majorly used in the medication of androgen-, estrogen-, and progestin-related hormonal diseases. Its molecular formula is C 15 H 22 O . Chemically, it is a terpene. Robinson annulation process is an effective process for the ring formation of six-membered polycyclic compounds, such as lipids and steroids. It works with three important steps, which are as follows: conjugate addition of resonance-stabilized carbanion, aldol condensation, and elimination of hydroxyl ion ( − OH ). Aldol condensation involves the addition of the aldol ( aldehyde and alcohol) group, followed by condensation of the product. In this reaction, the enolate of an aldehyde or a ketone reacts at the α − carbon with the carbonyl part of the other molecule to produce an β − hydroxy aldehyde or a ketone. Michael addition is a reaction that involves the conjugate addition of a resonance-stabilized carbanion for the formation of an enolate. The reaction thatinvolves the removal of an α − proton through a base is known as E1 elimination reaction. The reaction thatinvolves the removal of the − OH group through dehydration is known as E2 elimination reaction.

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.
