The oxidation of 3a,4-dihydro-1-isoindolinone derivatives with MCPBA was carried out regio- and stereoselectively to afford the 5,6-epoxide products 2. The ring opening reaction of 2 with amines, alcohols, and sodium azide gave homoallyl alcohol type of products, derived from the ring opening at C-5 of 2. Lithium (cyano-C)methylcuprate reacted with 2 to give homoallyl and/or allyl alcohol, which is
