A one-step method for the synthesis of aromatic indolizine derivatives byintramolecular 1,5-dipolar cyclization reaction of 2-(2-arylethenyl)pyridinium N-ylidesin the presence of an oxidant has been studied for the first time. In the presence ofelectron-deficient olefins, however, 2-(2-phenylethenyl)pyridinium N-ylides underwent1,3-dipolar cycloadditions and then aromatized in situ by TPCD to produce indolizinederivatives, indicating 1,3-dipolar cycloaddition proceed more readily than 1 ,5-dipolarcyclization in these conditions. Pyridinium disubstituted N-ylides, readily obtainedfrom corresponding pridinium and β-chlorovinyl ketone, underwent thermalintramolecular 1,5-dipolar cyclization to give indolizine derivatives easily.Indolizinecarbaldehyde derivatives were synthesized starting from 2-pyridinecarbaldehyde in four-steps involving 1,3-dipolar cycloaddition reaction.

Project activities included a nationwide survey on the driver's safety belt use rate of the passenger car, the test-driving of COROLLA of TOYOYA, which have equipped with the SBR system and the questionnaire form the drivers in the test. Base on the data, we get the effectiveness of the SBR system to the people of different classification, such as age, income and education etc. The results indicated that the most effective and acceptable safety-belt reminder system concept was one that was adaptive, that is, one that changes its signal type and presentation modality depending on belt use behavior over some metric. Ultimately, base on the fatal data of passenger car driver in the traffic accident of our country and the relationship of the safety belt use rate between the dead driver and the rate in our research, we got the number of life that can be saved in the traffic accident when the SBR system was used, and then the economic losing related was calculated.
