An efficient [3+2] cycloaddition of nitrones and carbodiimides has been developed. This 1,3-dipolar cycloaddition features high regioselectivity, mild and metal-free conditions, excellent functional group compatibility, and a broad substrate scope. The X-ray structures of two regio-isomers confirmed the regioselectivity of this transformation.
已开发出有效的[3 + 2]环硝基环和碳二亚胺。这种1,3-偶极环加成反应具有高区域选择性,温和且无金属的条件,出色的官能团相容性和广泛的底物范围。两种区域异构体的X射线结构证实了这种转化的区域选择性。
