The two enantiomers of the title dehydroamino acids (DHAAs) have been synthesized through respective Wadsworth–Emmons condensations of a suitable phosphonate with enantiomeric cyclobutyl aldehydes. These compounds, in turn, were prepared by selective manipulation of the functional groups starting from (−)-cis-pinononic acid as the common chiral precursor. The CD spectra of the prepared DHAAs are described
标题脱氢氨基酸(DHAAs)的两种对映体是通过合适的膦酸酯与对映体环丁醛的各自的Wadsworth-Emmons缩合反应合成的。这些化合物又是通过选择性操纵以(-)-顺式-己酸为常见手性前体的官能团制备的。描述了制备的DHAA的CD光谱。这些产品适用于立体控制合成不同类型的饱和环丁基氨基酸及其衍生物。
