A new shorter synthesis of 2-vinyl-3,4-dihydro-naphthalene has been described. The Diels-Alder reactions of this diene with 4-acetoxy-2-cyclopenten-1-one, 3-bromoindan-1-one and inden-1-one under high pressure conditions are reported. A two step synthesis of cyclopenta[c]-and indeno[c]phenanthrenones is discussed. Structure analysis by 1H and 13C NMR spectroscopy is presented.
已经描述了2-乙烯基-3,4-二氢萘的新的更短的合成。据报道,该二烯在高压条件下与4-乙酰氧基-2-环戊烯-1-酮,3-溴茚满-1-酮和茚满-1-酮的狄尔斯-阿尔德反应。讨论了环戊[c]-和茚并[c]菲咯酮的两步合成。介绍了通过1 H和13 C NMR光谱进行的结构分析。
