In the presence of a Lewis acid the phenol-Passerini three-component reaction (phenol-P-3CR) system is found to deliver a product of the phenol-Ugi four-component reaction (phenol-U-4CR). It is the first demonstration of an isocyanide as an amine equivale
Base-Promoted Reaction of O-Sulfonylated Hydroxamic Acids with Nucleophiles. A New Mehtod for the Synthesis of α-Substituted Amides

Treatment of a series of hydroxamic acids 2 with mesyl chloride in the presence of 2 equiv of triethylamine at 0 deg C gives 2-chloroamides 3 in good yields.Use of a single equivalent of triethylamine gives the N-(mesyloxy)amides 1, which are versatile sy
