[reaction: see text] 1,2,4-trioxepanes, readily prepared and easily handled derivatives of aldehydes and ketones, are stable to a variety of synthetic conditions and yet easily deblocked with Zn/HOAc or Mg/MeOH to regenerate the parent carbonyl. Trioxepanes may provide an alternative to 1,3-dithianes for acid-stable protection of carbonyl groups.
[反应:请参见文本] 1,2,4-三氧杂环丁烷是易于制备且易于处理的醛类和酮类衍生物,对多种合成条件稳定,但易于用Zn / HOAc或Mg / MeOH解封以再生母体羰基。三氧杂环丁烷可以为1,3-二硫杂环丁烷提供一个替代方案,以使酸稳定地保护羰基。
