Alkynyldimethylaluminum reagents react with various aromatic and aliphatic acidchlorides in a fast and efficient way. This reaction provides a simple entry to numerous ynones, using readily available, inexpensive, and nontoxic metalating agent, and does not require any transition metal as a catalyst.

A simple route for the synthesis of 1,3-diketones by the reaction of acetylenic ketones with amines followed by hydrolysis of the resulting aminovinylketons is suggested.
Total Syntheses of the Proposed Structure for Ieodoglucomides A and B
The firstenantioselective total synthesis of new glycolipopeptides, ieodoglucomides A and B, has been accomplished along with synthetic elaboration to their C14-epimers starting from d-glucose using β-glycosylation and Grubbs olefin cross-metathesis reactions as the key steps. The present synthetic study has indicated the ambiguity in proposed absolutestereochemistry for the natural product.
