Palladium catalyzed cycloisomerization of 1,6-enynes

학위논문 (석사)-- 서울대학교 대학원 : 화학부 무기화학 전공, 2013. 2. 정영근.A palladium-catalyzed cycloisomerization of 1,6-enynes, which can provide a variety of cyclic compounds, has been studied, The reaction pathway is highly dependent upon a leaving group of 1,6-enynes. Enynes with a phosphate leaving group gave rise to 5.7-bicyclic trienes and by an alkoxy group yielded monocyclic trienes. We also observed a Pd(∏)-catalyzed cycloisomerizaiotn of 1,6-enynes to bicyclo[4.1.0]heptenes in good yields under optimized conditions.Abstract …………3 Introduction ………………………4 Results and discussion ……………………8 Conclusion ……………………………………28 Experimental Section ………………………29 References ……………………………………63 국문초록 …………………………………68Maste
