Studies on azole-to-azole interconversions. Substituent effects on the ring-degenerate equilibration between 3-aroylamino-5-methyl-1,2,4-oxadiazoles and 3-acetylamino-5-aryl-1,2,4-oxadiazoles
involved. In the first case the effect of X is meagre and 3-acetylamino-5-aryl-1,2,4-oxadiazoles are more stable than the 3-aroylamino-5-methyl isomers. Vice-versa, when anions are involved the substituent effect is remarcable and the equilibrium can be, for strongly electron-withdrawing X-groups, even largely shifted towards the anions of the 3-aroylamino-5-methyl-1,2,4-oxadiazoles.
通过1 H NMR测量,已经在CD 3 OD和t BuOK / CD 3 OD中研究了标题反应。已经发现,无论涉及中性或阴离子形式,平衡组成和芳基部分中X-取代基对其施加的作用都完全不同。在第一种情况下,X的作用微不足道,3-乙酰氨基-5-芳基-1,2,4-恶二唑比3-芳酰基氨基-5-甲基异构体更稳定。反之亦然,当涉及阴离子时,取代基的作用是可区分的,并且对于强烈吸电子的X-基团,其平衡甚至可能朝着3-aroylamino-5-methyl-1,2,4-的阴离子转移。恶二唑。

An alkyne–isocyanide [3 + 2] cycloaddition followed by a Boulton–Katritzky rearrangement and a ring expansion is demonstrated. Different from the typical Boulton-Katritzky rearrangement, which forms five-membered ring products, the rearrangement-ring expansion method provides a mild, efficient, and atom-economical access to fused 9-deazaguanine structures in high yields.
