Diastereoselective Birch reduction−alkylation reactions of bicyclic β-alkoxy-α,β-unsaturated carbonyl compounds and tricyclic analogues were investigated. Although the relative configuration of the product was altered according to the structure of the starting material, stereoselectivity of the reaction could be accounted for by similar reaction pathways. The product from the tricyclic β-alkoxy-α,β-unsaturated
研究了双环β-烷氧基-α,β-不饱和羰基化合物和三环类似物的非对映选择性桦木还原-烷基化反应。尽管产物的相对构型根据起始材料的结构而改变,但是反应的立体选择性可以由相似的反应途径来解释。来自三环β-烷氧基-α,β-不饱和羰基化合物的产物对应于三茂金属骨架。
