GLC analyses were performed on a capillary gas chromatograph equipped with fused silica column (L 25 m, 0.20 mm i.d., 0.33 µm film thickness) at a helium pressure of 200 kpa, split less /split injector and flame ionization detector. Mass spectra were acquired on a GC-M instrument using a gas chromatograph equipped with fused silica column (L 30 m, 0.25 mm i.d., 0.25µm film thickness) and He as carrier gas. 1 H-NMR spectra were recorded on NMR spectrometers operating at 200 MHz and 400 MHz. Chemical shifts were referenced to internal TM. tarting materials and reagents were purchased commercially and used without further purification. All of the reaction products are previously reported in the literature. The reaction products were analyzed by GC and GC-M and by comparison with authentic samples. ilica gel 60 (0.040-0.0063 mm) was used for the flash chromatography. F-254 TLC plates were used in order to follow the progress of the reactions, the purity of substance and to identify the various fractions from the flash chromatography separation. The spots of substances on the thin-layer were visualized under UV light. Compound data.
