Abstract

Carbonylation reactions have been widely used to construct carbonyl-containing molecules or carbon enhancement reactions, which are mostly catalyzed by noble metals (Pd, Rh, Ru, Ir). In this review, we introduce the copper-catalyzed carbonylation reactions that have been developed in our group. Diverse reactions have been developed using various substrates, including the carbonylation of C–H activated alkanes, the difunctionalization of unsaturated C–C bonds, and the carbonylation of alkyl halides via the radical pathway. 1 Introduction 2 Cu-Catalyzed Carbonylation of C(sp3)–H Bonds 3 Cu-Catalyzed Carbonylative Difunctionalization of Unsaturated Bonds 4 Cu–X (H or B) Mediated Acylation of Unsaturated Bonds with Electrophiles 5 Cu–X (H or B) Mediated Carbonylation of Unsaturated Bonds 6 Cu-Catalyzed Carbonylation of Alkyl Halides 7 Other Types of Copper-Catalyzed Carbonylation Reactions 8 Conclusion and Outlook [ABSTRACT FROM AUTHOR]

Abstract

Anther dehiscence is a crucial event in plant reproduction, tightly regulated and dependent on the lignification of the anther endothecium. In this study, we investigated the rapid lignification process that ensures timely anther dehiscence in Arabidopsis. Our findings reveal that endothecium lignification can be divided into two distinct phases. During Phase I, lignin precursors are synthesized without polymerization, while Phase II involves simultaneous synthesis of lignin precursors and polymerization. The transcription factors MYB26, NST1/2, and ARF17 specifically regulate the pathway responsible for the synthesis and polymerization of lignin monomers in Phase II. MYB26‐NST1/2 is the key regulatory pathway responsible for endothecium lignification, while ARF17 facilitates this process by interacting with MYB26. Interestingly, our results demonstrate that the lignification of the endothecium, which occurs within approximately 26 h, is much faster than that of the vascular tissue. These findings provide valuable insights into the regulation mechanism of rapid lignification in the endothecium, which enables timely anther dehiscence and successful pollen release during plant reproduction.
