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.

A synthesis of the C(1)C(16) fragment 43 of the bryostatins is reported which features a stereoselective equivalent of an ‘ene’ reaction between the allylsilane 35 and the alkynone 33 and the stereoselective conjugate addition–cyclisation of the dienyl ketone 36 to give the acetal 39 after acetalisation.
Irreversible inhibitors of G12C mutant K-Ras protein are provided. Also disclosed are methods to modulate the activity of G12C mutant K-Ras protein and methods of treatment of disorders mediated by G12C mutant K-Ras protein.
