  摘要：

  Condensations of the chiral N-ferrocenylethylindoloazepines 4a,b, with the aldehydes 5, 13, 19, 29, and 32, led to tetracyclic vinylogous urethanes 6a,b and 7,14a and 14b,21a,c and 21b,d,30a and 31a, and 30b and 31b. Respectively, 6:1, 5:1, 3:1, 1.7:1, and 2:1 diastereomeric selections provided intermediates which, on cleavage of the chiral auxiliary N-substituent and subsequent elaboration of ring D of the Aspidosperma and Strychnos alkaloids, provided enantiomerically pure (-)-psi- and (-)-epi-psi-vincadifformines (1, 2), (+)-ibophyllidine (12), (+)-and (-)-vincadifformine (16a, 16b), (-)-tabersonine (27), and (-)-mossambine (41).

  The pentacyclic alkaloids vincadifformine (9), psi-vincadifformine (15), and epi-psi-vincadifformine (16) could be synthesized by intramolecular free-radical-induced cyclizations of the tetracyclic intermediates 7, 8, and 18, which were respectively obtained by condensation of the indoloazepine 1 with 2-(phenylselenyl)butyraldehyde and subsequent N-b-alkylation of the resulting tetracyclic amines 2 and 3, or from condensation of (phenylselenyl)acetaldehyde with the alkylated indoloazepine 17. The intermediates 2 and 3 also gave 3-oxovincadifformine (21) by an intermolecular radical alkylation with methyl acrylate. Their alkylation with (Z)-1,3-diiodopropene, phenyl selenoxide elimination, and intramolecular Heck reactions provided tabersonine (24) and 18,19-didehydrotabersonine (27).
