A Morita-Baylis-Hillman-type reaction has been applied to the asymmetric preparation of azaspirocycles in high yield and diastereoselectivity. The optimisation of the reaction is discussed and a model for the origin of diastereoselectivity is proposed.
森田-贝利斯-希尔曼型反应已被应用于高效和高立体选择性地不对称合成氮杂
螺环化合物。本文探讨了该反应的优化方法,并提出了一种解释立体选择性起源的模型。
