Abstract

The key transformation for the total synthesis of the lindenane sesquiterpenoid dimers is the intermolecular Diels–Alder reaction between two lindenane-type monomers. Herein we report our efforts made on examination of the biogenetic hypothesis and the inverse-electron-demand Diels–Alder (IEDDA) reaction. The combination of Tf2NH/AlMe3 was developed to catalyze the model IEDDA reaction.

Abstract

The article focuses on direct cyclopropylation of heterocycles catalyzed by palladium. Topic discussed include process of alkylation for unsaturated heterocycles catalyzed by palladium, addition of radical to heteroarenes, using of cyclopropyl iodides with heterocycles for radical process, orientation of cyclopropyl rings, cyclipropylation of various heterocycles like oxazoles, caffeine, and thiazoles, and Suzuki reaction of cyclopropyl halides.
