  The enantioselective Michael addition reaction of α-substituted cyclic ketones with acrylates was efficiently promoted by a primary amine chiral catalyst under high-pressure conditions (1.0 GPa) in tetrahydrofuran. This method was highly successful for the construction of an all-carbon-substituted quaternary-carbon stereogenic center at the α-position of cyclic ketones in high enantiomeric excess,

  在四氢呋喃中，在高压条件 (1.0 GPa) 下，伯胺手性催化剂有效地促进了 α-取代环酮与丙烯酸酯的对映选择性迈克尔加成反应。该方法在高对映体过量的环酮α位构建全碳取代季碳立体中心非常成功，可方便地应用于(+)-aspidospermidine的正式合成。

  N-Mesyloxylactams can undergo ring contraction either by C-3 (usually observed) or C-5 migration. C-5 migration can occur when the C-3 migration product possesses ring strain, but it does not usually compete with C-3 migration. The greater preference for C-3 migration is due to the carbonyl oxygen atom, which greatly stabilizes the intermediate.

  N-Mesyloxylactams 可以通过 C-3（通常观察到）或 C-5 迁移进行环收缩。当 C-3 迁移产物具有环应变时会发生 C-5 迁移，但它通常不与 C-3 迁移竞争。C-3 迁移的更大偏好是由于羰基氧原子，它极大地稳定了中间体。

With this system, initial protonation takes place on the more nucleophilic enol ether π-bond and the resulting carbonium ion undergoes a subsequent cyclization with the enamido π-bond to give the observed product. The electrophilic promoted cyclizations were extended to include the related hexahydro[1]pyrindinone and 1H-quinolinone systems. An NBS-promoted intramolecular electrophilic

  A cationic gold(I)/PPh3 complex catalyzes cycloisomerizations of bicyclic N-alkenyl alkynylamides leading to tricyclic 2-pyridone derivatives at room temperature in good yields. The bicyclic N-alkenyl alkynylamides are readily prepared starting from commercially available 2-substituted cycloalkanones.

  Tricyclic alkylamines, and their acid addition salts with pharmaceutically acceptable acids, are disclosed. The tricyclic ring system for these compounds is selected from the group consisting of 1,2,3,4-tetrahydrocyclopent[b]indole, 1,2,3,4-tetrahydrocarbazole and 5,6,7,8,9,10-hexahydrocyclohept[b]indole. The compounds are characterized further in that the ring system carbon atom bearing the alkylamine residue is carbon atom 3, 1 and 6 in the respective ring systems and in each case the said carbon atom also is substituted with a lower alkyl. The tricyclic alkylamines are useful antidepressant agents. Methods for their preparation and use are disclosed.
