Borylation of propargylic substrates by bimetallic catalysis. Synthesis of allenyl, propargylic, and butadienyl bpin derivatives

Bimetallic Pd/Cu and Pd/Ag catalytic systems were used for borylation of propargylic alcohol derivatives. The substrate scope includes even terminal alkynes. The reactions proceed stererospecifically with formal S N2′ pathways to give allenyl boronates. Opening of propargyl epoxides leads to 1,2-diborylated butadienes probably via en allenylboronate intermediate.

Combined rhodium/gold catalysis: From propargyloxiranes to 2,5-dihydrofurans in one pot

A new and efficient one-pot synthesis of 2,5-dihydrofurans from propargyloxiranes and arylboronic acids takes advantage of sequential rhodium-gold catalysis. The transformation proceeds with center-to-axis-to- center chirality transfer and tolerates a wide variety of electron-accepting or electron-withdrawing substituents at the arylboronic acid, as well as cyclic or acyclic propargyloxiranes.

Stereoselective synthesis of syn-configured α-allenols by rhodium-catalyzed reaction of alkynyl oxiranes with arylboronic acids

(Chemical Equation Presented) A rhodium-catalyzed reaction of alkynyl oxiranes with arylboronic acids affords syn-configured α-allenols with high diastereoselectivity. The reaction is initiated by addition of an arylrhodium(I) species onto the alkyne moie

Diastereoselective syn or anti opening of propargylic epoxides. Synthesis of α-allenic alcohols

Propargylic epoxides easily react with Grignard reagents and catalytic amounts of copper(I) salt to afford α-allenic alcohols. The reaction is highly diastereoselective and its stereochemical outcome (syn or anti isomer) can be fully controlled. The syn d
