Several endo-tricyclo[5.2.1.02,6]decan-10-ones and endo-tricyclo[5.2.1.02,6]dec-8-en-10-ones with hetero atom modifications at the distal C-4 position have been subjected to hydride reduction. π-Face selectivities in these systems are largely governed by the same electronic factors that were earlier identified in the case of the norbornyl system. A computational study demonstrates good predictability
在远端C-4位置具有杂原子修饰的几个内-三环[5.2.1.0 2,6 ] decan-10- one和内-三环[5.2.1.0 2,6 ] dec-8-en-10-one具有进行氢化物还原。这些系统中的π-表面选择性在很大程度上受先前在降冰片烯系统中所确定的相同电子因素的支配。一项计算研究表明,在半经验水平上具有良好的可预测性。
