Rationale behind observed stereoselectivity in hydroboration of ( + ) - α -Pinene should be provided. Concept introduction: Hydroboration-oxidation involves sequence of two reactions. The hydroboration stage involves treatment of alkene with diborane that generates alkyl borane. In second stage, hydrogen peroxide in alkaline medium is used to oxidize the alkyl borane produced in step 1 that leads to synthesis of alcohols from alkenes . Anti-Markovnikov’s rule serves as basis of hydroboration. It states that negative part of reagent must go to the carbon that has less alkyl substituents or more H atoms. This rule is followed in case of hydroboration reaction or reaction with peroxides.
