An organocatalytic version of the inverse-electron-demand Diels–Alder (IEDDA) reaction of 1,3,5-triazines was successfully developed. Hydrazine was used an effective organocatalyst for the direct IEDDA reaction of ketones with 1,3,5-triazines. This reaction has an expanded substrate scope relative to other 1,3,5-triazine IEDDA reactions and is also more operationally simple; thus, it is a succinct
成功开发了 1,3,5-三嗪的逆电子需求 Diels-Alder (IEDDA) 反应的有机催化版本。肼被用作一种有效的有机催化剂,用于酮与 1,3,5-三嗪的直接 IEDDA 反应。该反应相对于其他 1,3,5-三嗪 IEDDA 反应具有更大的底物范围,并且操作更简单;因此,它是一种从易得的酮类制备高度官能化嘧啶的简洁、经济且绿色的方法。
