A Convenient Synthesis of Masked β-Ketoaldehydes by the Controlled Addition of Nucleophiles to (Trimethylsilyl)ethynyl Ketones
摘要:
The controlled addition of nucleophiles to (trimethylsilyl)ethynyl ketones provides a facile route to beta-ketoacetals, beta-alkoxy-alpha,beta-unsaturated ketones or vinylogous amides depending on the choice of reaction conditions.
