Reaction of primary selenoamides with α,β-unsaturated ketones in the presence of BF3·Et2O provided 5,6-dihydro-4H-1,3-selenazine derivatives in high yields. Among the 1,3-selenazine diastereomers bearing two asymmetric carbons at the C4 and C6 positions, the cis form is predominant.
在BF3·Et2O的存在下,初级硒酰胺与α,β-不饱和酮的反应提供了高产率的5,6-二氢-4H-1,3-硒唑衍生物。在具有C4和C6位置两个不对称碳的1,3-硒唑二叠体中,顺式构型是主要的。
