1,1‐and 1,2‐Diborylalkenes: Preparation and Synthetic Applications

In this review, we highlight recent advances in the synthesis and reactivity of 1,1‐diborylalkenes and 1,2‐diborylalkenes, along with various transformations leading to CC, C‐heteroatom, and multicomponent products. The study covers both symmetrical and unsymmetrical strategies for synthesizing bis(boronates) from alkenes, alkynes, and carbonyl precursors, including metal‐catalyzed, base‐promoted, and organophosphorus‐mediated methods. In addition to demonstrating their versatility in building complex molecular frameworks for medicinal chemistry, alkenyl bis(boronates) are used in regioselective transformations. By providing a comprehensive and practical resource, this review aims to assist researchers in exploring the synthetic utility of 1,1 and 1,2‐alkenyl bis(boronate) compounds.
