A connective synthesis of substituted hydrindanones and decalones can be accomplished based upon a novel approach involving two key-steps: a Morita–Baylis–Hillman condensation and an intramolecular reductive cyclisation using lithium in ammonia. Decalones, akin to the middle core of the clerodane family of natural products and bearing a quaternary carbon centre, can be readily assembled via this protocol
取代的氢化氢酮和癸酮的连接合成可以基于涉及两个关键步骤的新方法来完成:森田-贝利斯-希尔曼缩合反应和氨中锂的分子内还原环化反应。通过该协议,可以很容易地组装类似于癸二烷天然产物中间核并带有四级碳原子中心的十足鸟。
