Procedure: To a solution of 1.61 g (5.0 mmol) of 3-[4-(imidazo[1,2-a]pyridin-5-ylthio)butyl]thiazolidine-2,4-dione and 0.711 g (5.0 mmol) of 1-nonanal in 20 ml of ethanol, 0.05 ml (0.5 mmol) of piperidine was added, followed by refluxing for 1.5 hours. After the reaction mixture was cooled, the solvent was distilled off. The residue was dissolved in dichloromethane, washed with water and dried, after which the solvent was distilled off. The residue was purified by column chromatography (eluent, n-hexane/ethyl acetate=3/1) to yield 1.96 g (88.0%, yellow oily substance) of the desired product. by refluxing for 1.5 hours After the reaction mixture was cooled the solvent was distilled off The residue was dissolved in dichloromethane washed with water dried after which the solvent was distilled off The residue was purified by column chromatography (eluent, n-hexane/ethyl acetate=3/1)

Procedure: Targets are complementary oligonulceotides labeled with fluorescent dye Cy3. Slides were hybridized with targets in hybridization buffer (2×SSC, 0.1% SDS and complementary target at 100 nM) at room temperature for 1 hr and washed in 2×SSC, 0.1% SDS for 5 min., 0.1×SSC, 0.1% SDS for 10 min., and finally in 0.1×SSC for 1 min. All washings were carried out at room temperature. Results show that the aldehyde slides prepared from photoactivatable silane gave much higher hybridization signal than non-aldehyde slides. washed in 2×SSC, 0.1% SDS for 5 min. finally in 0.1×SSC for 1 min were carried out at room temperature Results

Procedure: A 300-mL stainless steel autoclave equipped with a magnetically driven stirrer was charged under nitrogen with rhodium (14.55 mg of rhodium, 0.14 mmole charged as the 2-ethylhexanoate salt), α,α'-bis(diphenylphosphino)-o-xylene ligand (0.16 gm, 0.34 mmole), 1-octene (22.44 grams), and toluene (70 mL). This was pressured to 300 psig with a 1/1 mixture of hydrogen/carbon monoxide (synthesis gas) and heated to 105° C. The autoclave was repressured to 300 psig with the synthesis gas mixture whenever the pressure dropped to 250 Psig. The reaction was kept at 105° C. for 2 hours, during which time a total pressure drop of 460 psig was observed. The mixture was analyzed by gas/liquid chromatography and showed a 94.3 percent conversion of 1-octene. A 90.6 percent yield to isomeric nonanal products was obtained based on 1-octene charged. The ratio of linear/branched nonanal product was 3.47/1. The autoclave was repressured to 300 psig with the synthesis gas mixture whenever the pressure dropped to 250 Psig

Procedure: 1-Decene was supplied from a raw-material tank 4 using a high-pressure pump, and the raw material was preheated in an ozonization reaction vessel 3 at 20° C. The preheated raw material was then combined with the high-pressure carbon dioxide solution of ozone, and continuous ozonization proceeded in a stainless steel coil-shaped ozonization reaction section 1 having an inside diameter of 1 mm and a length of 26 cm and set to 20° C. The reaction mixture that exited from the ozonization vessel 3 was subsequently subjected to a continuous thermal decomposition reaction in a stainless steel coil-shaped decomposition reaction section 11 having an inside diameter of 1 mm and a length of 100 cm and set to 200° C. The residence time corresponding to the reaction time was 6 seconds in the ozonization reaction section and 24 seconds in the decomposition reaction section, making a total of 30 seconds. The product was passed via the pressure-regulating valve 30 and was dissolved in acetone placed in a gas-liquid separation device 40. Quantification of the acetone solution by FT-NMR using coumarin as an internal standard confirmed that 0.58 mmol of nonanoic acid and 0.63 mmol of nonanal were produced in 30 minutes. set to 20° C set to 200° C The residence time corresponding to the reaction time was 6 seconds in the ozonization reaction section and 24 seconds in the decomposition reaction section a total of 30 seconds placed in a gas-liquid separation device 40

Procedure: As an example, oleic acid can be oxidatively cleaved into nonanal (m.p. −18° C., b.p. 195° C.) and oxononanoic acid (m.p. 70° C., b.p. 181-182° C.) with oxygen, air or hydrogen peroxide. Nonanal can be utilized as is or converted to nonanol (m.p. −7° C., b.p. 215° C.) by catalytic hydrogenation. The nonanal can be distilled off and the high melting oxonanoic acid can be converted to an ester by reaction with bio-derived ethanol to produce ethyl 9-oxononanoate (m.p. 5° C.). The following represents the reaction scheme: The nonanal can be distilled off can be converted to an ester by reaction with bio-derived ethanol
