Phenols are ethynylated at the ortho position with silylated chloroethyne in the presence of a catalytic amount of GaCl3 and lithium phenoxide. The lithium salt is essential for the catalysis, and addition of 2,6-di(tert-butyl)-4-methylpyridine inhibits desilylation and hydration of the

Regioselectivity of Ln(OTf)3-catalysed alcoholysis of 2,3- and 3,4-epoxy alcohols was closely investigated to expand the scope of the transformations. The synthetic use was demonstrated by application to the construction of 4-propoxy-5-hydroxy-2,3-pentanedione (C4-propoxy-HPD), which is a potent synthetic mediator in AI-2
