โœฆ Synopsis

Indium mediated allylation and propargylation reactions of acetals and ketals with various allyl or propargyl bromides in aqueous media successfully provided the corresponding homoallylic or homopropargylic (and allenylic) alcohol, respectively, in moderate to good yields. Highly chemoselective allylation is also described. The ketal and aryl acetal could be selectively allylated over the aliphatic one in 80-84% yields.

Allylation and propargylation of compounds, 6-oxopenicillanate 1 and 7-oxocephalosporanate 2, were accomplished by reacting the corresponding bromides in the presence of indium or zinc. Both indium and zinc gave alkylated products in moderate yields under mild conditions. Indium mediated Barbier rea
