Total Synthesis of Olivacine and Ellipticine via a Lactone Ring-Opening and Aromatization Cascade

Autor: Tahir Tilki, Erkan Ertürk, Ömer Dilek, Süleyman Patir

Publikováno v: The Journal of Organic Chemistry. 84:7901-7916

Effective preparation of olivacine and ellipticine via late-stage D-ring cyclization is described. Key features of the synthetic routes include trifluoroacetic acid-mediated formation of a lactone that is fused to a tetrahydrocarbazole derivative and

Chiral 1,4-aminoalkylphenols for enantioselective diethylzinc addition toaldehydes

Autor: Tahir Tilki, Ömer Dilek, Erkan Ertürk, Mustafa A. Tezeren

Publikováno v: TURKISH JOURNAL OF CHEMISTRY. 43:612-623

Starting from a chiral secondary alcohol, novel enantiopure 1,4-aminoalkylphenols (AAPs) were prepared by exploiting conventional organic transformations such as the Mitsunobu reaction, Eschweiler--Clarke N-methylation, and demethylation of anisoles.

Enantioselective Synthesis of 1- and 4-Hydroxytetrahydrocarbazoles through Asymmetric Transfer Hydrogenation

Autor: Erkan Ertürk, Ömer Dilek, Süleyman Patir

Publikováno v: Synlett. 30:69-72

Several 1- and 4-hydroxytetrahydrocarbazoles were prepared in high yields (up to 99%) and excellent enantiomeric excesses (up to >99% ee) from the corresponding 1- and 4-oxotetrahydrocarbazoles through asymmetric transfer hydrogenation by using the c

Chiral 2-(2-hydroxyaryl)alcohols (HAROLs) with a 1,4-diol scaffold as a new family of ligands and organocatalysts

Autor: Tahir Tilki, Erkan Ertürk, Mustafa A. Tezeren, Ömer Dilek

Publikováno v: Tetrahedron. 74:268-286

Efficient and modular syntheses of chiral 2-(2-hydroxyaryl)alcohols (HAROLs), novel 1,4-diols carrying one phenolic and one alcohol hydroxyl group, have been developed which led to generation of a small library of structurally diverse HAROLs in enant

Synthesis, solvatochromic properties and theoretical calculation of some novel disazo indole dyes

Autor: Çiğdem Karabacak, Ömer Dilek

Publikováno v: Journal of Molecular Liquids

Synthesis of new disazo indole dyes (3a-3m) was carried out by diazotization of 5-amino-4-arylazo-3-methyl-1H-pyrazoles (2a-2m) and coupling with 2-phenyl indole. The newly synthesized 12 disperse disazo dyes were characterized by UV-vis, FT-IR, H-1
