Oxiranes undergo ring opening through a nucleophilic attack. The three remembered ring is unstable, the oxygen is electron withdrawing group making the carbons attached to it electrophile. Write the reaction mechanism for each one of the reactions below. • Cyanide ion is a good nucleophile, it will attach the less substituted carbon to open the ring. A second reaction (H30+) is used to protonate the oxygen to give the alcohol. • Chloride ions is a moderate nucleophile. Protonate oxygen in the first step and open the ring by chloride ion attack on the carbon that better bears the positive charge (the more substituted). 1. NaCN H₃0t 2. HCI

Write out the complete synthesis on a separate sheet of paper, and then draw the structure of the product of step 1. • Use the wedge/hash bond tools to indicate stereochemistry where it exists. . If the reaction produces a racemic mixture, draw both stereoisomers, • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. • Separate multiple products using the + sign from the drop-down menu.
