A methodology for the synthesis of terminally substituted [3]‐ and [4]dendralenes, as well as 2,3‐disubstituted buta‐1,3‐dienes has been prepared. This involves the preparation of 1,2‐disubstituted cyclobutenes from readily available 2‐bromocyclobutanone and the subsequent thermal ring‐opening reactions.
制备了末端取代的[3]-和[4]树枝状烯类以及2,3-二取代的buta-1,3-二烯的合成方法。这涉及从容易获得的2-溴环丁酮制备1,2-二取代的环丁烯,以及随后的热开环反应。
