    A facile synthesis of heterotricycles from furfurylbromoalkenes using thermal IMDA cycloaddition
    (FREUND PUBLISHING HOUSE LTD, 2006) Demircan, Aydm; Karaarslan, Muhsin; Turac, Ersen
    A variety of key precursors to the IMDA reaction of furan diene have been prepared via facile alkylation. Subsequently, rigid tricyclic compounds (2a-g) possessing oxygen, nitrogen, and sulfur has been synthesized by employing thermal intramolecular Diels-Alder reactions. These heterocyclic fused tricycles include a bromo quaternary carbon centre obtained stereoselectively with moderate yields (32-44 overall).

    The molecular structure and vibrational spectrum of 6-bromo-8-thia-1,4-epoxybicyclo[4.3.0] non-2-ene
    (MDPI AG, 2007) Arslan, Hakan; Demircan, Aydm
    Geometric parameters and FT-IR spectrum of 6-bromo-8- thia-1,4-epoxybicyclo[ 4.3.0]non-2-ene were computed by the HF, B3LYP, B3PW91 and mPW1PW91 methods in conjunction with the 6-31G(d,p) basis set. The calculated IR spectra are in a good agreement with the observed FT-IR spectrum. A general better performance of B3LYP, B3PW91 and mPW1PW91 versus HF was quantitatively characterized by using PAVF 1.0 program. Optimal uniform scaling factors calculated for the title compound are 0.8952, 0.9552, 0.9520 and 0.9456 for HF, B3LYP, B3PW91 and MPW1PW91 methods, respectively.
