Acylation of 4-substituted 1-trimethylsilylbuta-1,3-diynes (2) with suitable acyl halides in the presence of titanium tetrachloride gave diacetylenic ketones (3) including the naturally occurring compounds (3c), (3e), and (3f). ... This represents a 50% yield of (3c) plus a 10% yield of EtCO---( ...
