Başçeken, Sinan; Kaya, Serdal; Balcı, Metin (American Chemical Society, 2015)Gold-catalyzed and NaH-supported intramolecular cyclization of N-propargyl indole derivatives with pyrazole and pyrrole units attached to indole is described. An efficient route to the synthesis of pyrazolodiazepinoindole, ... -
Nucleophilic and electrophilic cyclization of N-alkyne-substituted pyrrole derivatives: Synthesis of pyrrolopyrazinone, pyrrolotriazinone, and pyrrolooxazinone moieties
Yenice, Işıl; Başçeken, Sinan; Balcı, Metin (Beilstein-Institut Zur Forderung der Chemischen Wissenschaften, 2017)Intramolecular nucleophilic and electrophilic cyclization of N-alkyne-substituted pyrrole esters is described. Efficient routes towards the synthesis of pyrrolopyrazinone, pyrrolotriazinone and pyrrolooxazinone have been ... -
Study of asymmetric aldol and Mannich reactions catalyzed by proline-thiourea host-guest complexes in nonpolar solvents
Demir, Ayhan Sıtkı; Başçeken, Sinan (2013)A proline-thiourea host-guest complex has been described as a good catalyst for asymmetric reactions such as aldol and Mannich reactions. High stereoselectivities were obtained under optimal conditions. Thiourea was observed ... -
Synthesis of a bipyridine-derived achiral thiourea trifluoromethanesulfonic acid salt and its application as an additive in organocatalytic asymmetric reactions
Demir, Ayhan Sıtkı; Başçeken, Sinan (2013)The host-guest complex of a proline-thiourea bipyridine trifluoromethanesulfonic acid salt can catalyze organocatalytic asymmetric reactions such as aldol, Michael, and Mannich in polar protic medium with high stereoselectivities. ... -
Synthesis of pyrrolo-pyrrolo-pyrazines via the Pd/C-catalyzed cyclization of N-propargyl pyrrolinyl-pyrrole derivatives
Aslanoğlu, Furgan; Başçeken, Sinan; Balcı, Metin (Elsevier Ltd, 2019)A novel and efficient synthesis of N-substituted dipyrrolo[1,2-a:2',1'-c]pyrazine derivatives has been developed. The synthetic strategy relies on the synthesisof 4',5'-dihydro-1H,3'H-2,2'-bipyrrole, followed by the reaction ...
