The [3,3′(4H,4′H)‐bi‐2H‐1,3‐oxazine]‐4,4′‐diones 3a–3i were obtained by [2+4] cycloaddition reactions of furan‐2,3‐diones 1a–1c with aromatic aldazines 2a–2d (Scheme 1). So, new derivatives of bi‐2H‐1,3‐oxazines and their hydrolysis products, 3,5‐diaryl‐1H‐pyrazoles 4a–4c (Scheme 3), which are potential biologically active compounds, were synthesized for the first time.
的[3,3'(4 ħ,4' ħ)-bi-2 ħ -1,3-恶嗪] -4,4'-二酮3A - 3I是由[2 + 4]环加成的呋喃-2-反应获得,3-二酮1a - 1c与芳族醛嗪2a - 2d(方案1)。因此,首次合成了潜在的生物活性化合物bi-2 H -1,3-恶嗪的新衍生物及其水解产物3,5-二芳基-1 H-吡唑4a - 4c(方案3)。时间。
