straightforward synthesis of α-keto amides by coupling primary amines with aryl dibromoethanones under oxidative amidation conditions has been developed. The α-keto amides were then subjected to heterocyclodehydration reaction under Bischler-Napieralski conditions followed by aromatization with DBU provided 1-benzoyl isoquinolines in a two-stage process. Utilizing this methodology, isoquinoline alkaloids such
已经开发出通过在氧化酰胺化条件下将伯胺与芳基二溴乙酮偶联来直接合成 α-酮酰胺。然后将 α-酮酰胺在 Bischler-Napieralski 条件下进行杂环脱水反应,然后在两阶段过程中用 DBU 芳构化提供 1-苯甲酰基异喹啉。利用这种方法,异喹啉生物碱如沙米克林酮、罂粟碱和普氏碱 A 以极好的收率合成。
Co(III)-Catalyzed Annulative Vinylene Transfer via C–H Activation: Three-Step Total Synthesis of 8-Oxopseudopalmatine and Oxopalmatine
with vinylene carbonate for the synthesis of isoquinolinones and pyridinones has been developed. This protocol employing inexpensive Co(III) as the catalyst tolerated diverse functional groups and substitution patterns, affording the target products with good to excellent yields. The synthetic utility of this transformation was demonstrated by a three-step synthesis of gusanlung D, 8-oxopseudopalmatine
Herein, a novelclass of tetrahydroisoquinoline stilbene derivatives were synthesized, and their potential in vitro anticancer activities were evaluated. Most of the compounds displayed inhibitory activity against one or more representative human cancercell lines (lung cancer A549 cells, breast cancer MCF-7 cells, and human colorectal carcinoma HT-29 cells), especially compound 16e, which exhibited

Herein, a structurally novel class of histone deacetylase (HDAC) inhibitors featuring the C-1 phenyl substituted tetrahydroisoquinoline Cap moiety were designed, synthesized, biologicallyevaluated in vitro and structure-activity relationship (SAR) study. A majority of compounds exhibited potent inhibitory activity against both HDAC6 and HDAC1 with IC50 in the two-digit nanomolar. The representative
