Chiral alkoxyacetylenes

An enantiosdective intermolecular Pauson-Khand reaction between nor-bomene and chiral alkoxyacetylene bearing 10-methylthioisobomeol as the auxiliary has recently been successfully performed with high selectivity [1676]. [Pg.636]

Nucleophilic reagents usually attack the a-carbon of alkoxyacetylenes (equation 49). A large number of reactions of acetylenic ethers with such nucleophiles as amines, water, alcohols, thiols and organolithium compounds have been reported in previous reviews. More recent examples are reactions of phosphorylated alkoxyacetylenes with amines or alcohols (equation 53) and the reduction of chiral acetylenic ethers with LiAlH4 to enol ethers". ... [Pg.1152]

A convenient synthesis of Co2(CO)6 complexes of chiral (non-racemic) terminal alkoxyacetylenes has been reported . ... [Pg.376]
