A four‐component reaction for the synthesis of heterocyclic boronates is reported. Readily available hydrazides, α‐hydroxy aldehydes, and two orthogonally reactive boronic acids are combined in a single step to give structurally distinct bicyclic boronates, termed dioxadiazaborocines (DODA borocines). In this remarkable process, one boronic acid reacts as a carbon nucleophile and the other as a boron

Multicomponent Petasisreactions: The first diastereoselectivePetasisreaction catalyzed by chiral biphenols that enables the synthesis of syn and anti β‐amino alcohols in pure form has been developed. The reaction exploits a multicomponent approach that involves boronates, α‐hydroxy aldehydes, and amines (see scheme).

Allenes are useful functional groups in synthesis as a result of their inherent chemical properties and established reactivity patterns. One property of chemical bonding renders 1,3-substituted allenes chiral, making them attractive targets for asymmetric synthesis. While there are many enantioselective methods to synthesize chiral allenes from chiral starting materials, fewer methods exist to directly
