Paragraph 0234; 0235; 0236, (2018/07/30)
The invention discloses a method for the synthesizing a compound as shown in a formula I which is described in the specification. The method comprises a step of subjecting a compound II, a compound III and a compound IV to reaction in the presence of a catalyst to form the compound as shown in the formula I, wherein the compound II is one selected from compounds as shown in a formula II; the compound III is at least one selected from compounds as shown in a formula III-1 and a formula III-2; the compound IV is one selected from compounds as shown in a formula IV; R3 and R4 are independently selected from a group consisting of an alkyl group, a substituted alkyl group, a heteroaryl group and a substituted heteroaryl group.

N-Methyl ortho-carbamoylaryl benzyl sulfoxides can be used as synthetic equivalents for α-hydroxy, α-chloro, and α-acetammido benzyl carbanions by means of a two-step sequence involving highly diastereoselective α-C-alkylation with alkyl halides followed by displacement of the sulfinyl residue (which can be recovered and recycled) by a hydroxyl, a chlorine or an acetamido, respectively, under non-oxidative Pummerer conditions. The scope and limits of the method, including a stereoselective version of the reaction, as well as the mechanism of the process are discussed in detail.

Simple organic acids like 2,4-dinitrobenzenesulfonic acid (DNBSA) catalyze the Ritter reaction of secondary benzylic alcohols giving rise to the corresponding N-benzylacetamides in usually high yields. Reactions can be conducted without exclusion of oxygen and without the need of dry solvents. With tertiary α,α-dimethylbenzylic alcohols a different pathway involving a formal dimerization reaction takes place under the acid-catalytic conditions used. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.
