Identifying the needs of a target groupanched substituent was produced with moderate ee values. This indole formation was applicable to the synthesis of indole-fused polycyclic compounds via palladium-catalyzed C–H functionalization at 3-position of indole. Synthetic application to calindol, benzo[.][1,2]thiazines, and indene was also conducted.作者: Baffle 時間: 2025-3-23 03:46 作者: 大看臺 時間: 2025-3-23 05:55 作者: 臭了生氣 時間: 2025-3-23 10:06 作者: Cpap155 時間: 2025-3-23 16:40

Book 2011e first example of a three-component indole formation without producing salts as a byproduct. Based on this reaction, a copper-catalyzed synthesis of 3-(aminomethyl)isoquinoline was accomplished which represents an unprecedented isoquinoline synthesis through a four-component coupling reaction.

Treatment of 2-ethynylbenzaldehydes with paraformaldehyde, secondary amine, and .-BuNH. in the presence of a catalytic amount of CuI in DMF affords 3-(aminomethyl)isoquinolines in good yields, through successive formation of one carbon–carbon and three carbon–nitrogen bonds.作者: 里程碑 時間: 2025-3-25 13:43
Evaluating the outcomes of a group programmeon, has been developed. A Mannich-type reaction with 2-ethynylbenzaldehyde, paraformaldehyde, and a secondary amine followed by treatment with a diamine component gave tricyclic isoquinolines through cascade cyclization and oxidation. Construction of fused isoquinolines of various ring sizes is also presented.作者: innovation 時間: 2025-3-25 18:07
