“…1,3-Dipolar cycloadditions involving oxidopyridinium betaines have previously been used in alkaloid synthesis. [99] Gin and co-workers fully illustrated the value of this dearomatization approach in a complex setting during their elegant synthesis of (AE )-hetisine (63; Scheme 41). [100] In this Scheme 39.…”

Evolution in the field of the total synthesis of natural products has led to exciting developments over the last decade. Numerous chemo-selective and enantioselective methodologies have emerged from total syntheses, resulting in efficient access to many important natural product targets. This Review highlights recent developments concerning dearomatization, a powerful strategy for the total synthesis of architecturally complex natural products wherein planar, aromatic scaffolds are converted to three-dimensional molecular architectures.

Auf dem Gebiet der Totalsynthese von Naturstoffen hat es in den vergangenen zehn Jahren hochinteressante Entwicklungen gegeben. Zahlreiche chemoselektive und enantioselektive Methoden sind aus Totalsynthesen hervorgegangen und ermöglichten einen effizienten Zugang zu vielen wichtigen Naturstoffen. Dieser Aufsatz gibt einen Überblick über neuere Entwicklungen bezüglich der Desaromatisierung, die eine leistungsfähige Strategie zur Totalsynthese von strukturell komplexen Naturstoffen ist und bei der planare aromatische Vorstufen in dreidimensionale Molekülstrukturen umgewandelt werden.

An efficient strategy has been established for the enantiodivergent synthesis of natural product inspired compounds embodying both tropane and pyrrolidine natural product fragments.T his strategy includes the enantioselective kinetic resolution of racemic tropanes by means of acopper(I)catalyzed[ 3 + +2] cycloaddition and allows the preparation of two enantiopure products in ao ne-pot reaction in high yield and with high diastereo-and enantioselectivity by using one chiral catalyst.
