the first time by X‐ray structural analysis. The ortho‐methoxymethyl group and the carbonyl oxygen coordinate to the iodine atom of the iminoiodinane. Activation of the N‐acyliminoiodinane was achieved by photoirradiation at 370 nm, thereby enabling reaction with various silyl enol ethers to give α‐aminoketone derivatives in good to high yield. N‐sulfonyliminoiodinanes bearing ortho substituents were
X射线结构分析首次表征了N-环戊碘烷。的邻-甲氧基和羰基氧坐标到iminoiodinane的碘原子。通过在370 nm处进行光辐照可以实现N-酰基亚氨基碘的活化,从而使其能够与各种甲硅烷基烯醇醚反应,从而以高至高收率得到α-氨基酮衍生物。带有邻位取代基的N-磺酰亚胺基碘烷在光诱导的胺化反应中被使用。
