asymmetric allylic amination using a chiral diaminophosphine oxide (DIAPHOX) preligand and diastereoselective intramolecular Mannich reaction. The developed synthetic method could be applied to the catalytic asymmetric synthesis of (+)-2-epi-cis-195A. asymmetric allylic amination - asymmetric synthesis - chiral diaminophosphine oxide - decahydroquinoline alkaloid - intramolecular Mannich reaction - palladium
描述了对映选择性合成2-取代的六氢喹啉-4-酮的新方法。该方法依赖于使用手性二氨基膦氧化物(DIAPHOX)预配体和非对映选择性分子内曼尼希反应的钯催化的不对称烯丙基胺化。所开发的合成方法可应用于催化不对称合成(+) - 2-外延-顺-195A。 不对称的烯丙基胺化反应-不对称的合成-手性二氨基氧化膦-十氢喹啉生物碱-分子内曼尼希反应-钯
