Dipolar Cycloaddition Approach toward Harmicine-Type Alkaloids: Synthesis and Stereochemical Determination
A rapid synthesis of harmicine was achieved through 1,3-dipolar cycloaddition and facile ring reconstruction, including mesylation, cleavage of the N–O bond, and subsequent cyclization. An enzymatic kinetic resolution was developed to obtain optically enriched tetrahydro-β-carboline, which was further elaborated to prepare harmicine. Additionally, diastereomeric synthesis of harmicinic acid was also achieved, and stereochemical determination was enabled by chemical resolution and electronic circular dichroism calculations for the first time, providing an intriguing platform to access various derivatives for future medicinal research.
期刊介绍:
Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
