single diastereoisomer. That compound reacted with different organometallics leading to 3 in excellent de. Hydrolysis of carbinols, followed by oxidation of the intermediates allowed for the synthesis of enantiopure phthalides.
(-)-8-苄基氨基薄荷醇与邻苯二甲醛的缩合导致手性过氢-1,3-苯并恶嗪2为单一非对映异构体。该化合物与不同的有机金属反应生成3的优异de。甲醇的水解,然后氧化中间体,可以合成对映体纯的邻苯二甲酸酯。
