The oxidation of a range of cyclic allylic alcohols and amides with OsO4/TMEDA is presented. Under these conditions, hydrogen bonding control leads to the (contrasteric) formation of the syn isomer in almost every example that was examined. Evidence for the bidentate binding of TMEDA to OsO4 is presented and a plausible mechanism described.

使用OsO4 / TMEDA对环状烯丙基醇和三氯乙酰胺进行直接二羟基化。

提出了用OsO4 / TMEDA氧化一系列环状烯丙基醇和酰胺的方法。在这些条件下，几乎在每个所研究的实施例中，氢键控制导致顺式异构体的（对映体）形成。提供了TMEDA与OsO4的双齿结合的证据，并描述了一个可能的机制。
