The synthesis of compound 1 has to be shown from alkenes 2 and 3. Concept Introduction: Simmons–Smith reaction: It involves reaction of alkenes with organozinc reagent namely ICH 2 ZnI which results in formation of three–membered ring in product. This is a concerted reaction in which the configuration of starting alkene is preserved. Swern oxidation: Primary and secondary alcohols undergoes oxidation reaction using dimethyl sulfoxide, oxalyl chloride and triethyl amine which provides aldehyde and ketones . Wittig Reaction: It is an organic reaction where an aldehyde or a ketone gets converted to an alkene by replacing carbonyl group by a C=C bond. A phosphorous ylide is used for this conversion. It is a neutral molecule where a positively charged phosphorous is attached to a negatively charged carbon atom. Grubbs catalyst: This catalyst is used to achieve alkene metathesis. It contain transition metal namely Ru which is doubly bonded with carbon atom. Dienes in presence of Grubbs catalyst, alkene metathesis serve as method of ring formation.
