Publication Metadata only Synthesis and rearrangement reactions of 1,4-dihydrospiro[1,4-methanonaphthalene-9,1′-cyclopropane] derivatives(2018-10-04T00:00:00Z) Bayrak, Cetin; Senol, Halil; Sirtbasi, Sedef; Şahin, Ertan; Menzek, Abdullah; ŞENOL, HALILPublication Metadata only Synthesis of Oleanolic Acid Analogues and Their Cytotoxic Effects on 3T3 Cell Line(2018-01-01) Tuncay, Salih; Kocyigit, ABDÜRRAHİM; SEÇEN, Hasan; Ocal, Nuket; Topcu, GÜLAÇTI; Guler, ERAY METİN; ŞENOL, HALIL; GÜLER, ERAY METİN; KOÇYİĞİT, ABDÜRRAHİM; TOPÇU, GÜLAÇTIBackground: Oleanolic acid (OA) is a known natural compound with many important biological activities. Thirteen oleanolic acid derivatives linked at C-3 and C-28 were synthesized and their structures were confirmed by H-1- and C-13 NMR and mass spectral analyses. Among them, compounds 4, 6, 8-10, 12, 13 were synthesized for the first time. They were evaluated for their cytotoxic activity. They showed proliferative effect at low concentrations while cytotoxic effect was observed at high concentrations in a dose dependent manner.Publication Metadata only Synthesis and initial evaluation of efficacy of olean-12-en-28-ol, 3 beta-pentacosanoate for the symptomatic treatment of multiple sclerosis(2019-07-01) DAĞ, AYDAN; Sen, A.; ŞENOL, HALİL; Kale, E.; TOPÇU, GÜLAÇTI; ŞENOL, HALIL; DAĞ, AYDAN; TOPÇU, GÜLAÇTIPublication Metadata only Cycloaddition reaction of spiro[2.4]hepta-4,6-dien-1-ylmethanol and PTAD: a new rearrangement(2016-05-19T00:00:00Z) Senol, Halil; Bayrak, Cetin; Menzek, Abdullah; Şahin, Ertan; Karakus, Murat; ŞENOL, HALILReaction of spiro[2.4]hepta-4,6-dien-1-ylmethanol (3) with phenyltriazolinedione (PTAD) gave 4-phenyl-1-[(3aR(S),6S(R))-1a, 2,3a, 6-tetrahydro-1H-cyclopenta[b]cyclopropa[c]furan-6-yl]-1,2,4-triazolidine-3,5-dione (7) via a novel rearrangement. The structure of this rearranged product was determined by spectroscopic methods and by experimentation. Influences of functional groups on the rearrangement and formation of 7 were discussed.
