Thermal electronic ring-opening of 4-alkyl-2-cyclobutene-1-carbaldehydes occurs at low temperature to give (2Z,4E)-alka-2,4-dienals exclusively, and this process is exploited en route to various isomeric naturally occurring 1,3,5-alkatrienes and 2,4-decadienoates from a single precursor, cis-3-cyclobutene-1,2-dimethanol 4.
的4-烷基-2-环丁烯-1- carbaldehydes热电子开环发生在低温下,得到(2- Ž,4 ê)-alka -2,4- dienals排他地,并且这个过程被利用途中至各种同分异构天然存在的1,3,5-链烷烃和2,4-癸二烯酸酯,来自单个前体,顺式-3-环丁烯-1,2-二甲醇4。
