In the presence of Na2CO3, the [3+2] cycloaddition of azaoxyallyl cations in situ formed from α-halohydroxamates with isothiocyanides proceeded smoothly and furnished (Z)-2-iminothiazolidin-4-ones in 25-99% chemical yields. The chemical structure of title compounds was firmly confirmed by an X-ray single crystal structure analysis.
在 Na2CO3 存在下,由 α-卤代异硫氰酸盐与异硫氰化物形成的氮氧烯丙基阳离子的 [3+2] 环加成反应顺利进行,并以 25-99% 的化学产率提供 (Z)-2-iminothiazolidin-4-ones。通过 X 射线单晶结构分析确定了标题化合物的化学结构。
