Zhang, Zhenhao; Sabat, Nazarii; Frison, Gilles; Marinetti, Angela; Guinchard, Xavier published an article in 2022. The article was titled 《Enantioselective Au(I)-Catalyzed Multicomponent Annulations via Tethered Counterion-Directed Catalysis》, and you may find the article in ACS Catalysis.Category: ethers-buliding-blocks The information in the text is summarized as follows:
Gold(I) complexes of a chiral phosphoric acid-functionalized phosphine of the CPA-Phos series enable the enantioselective multicomponent reactions between aldehydes, hydroxylamines, and cyclic yne-enones, leading to 3,4-dihydro-1H-furo[3,4-d][1,2]oxazines. This represents a rare example of a highly enantioselective multicomponent reaction in gold(I) catalysis. The reactions proceed at a low catalyst loading and provide high yields, total diastereoselectivity, and enantiomeric excesses up to 99%. Silver-free conditions was applied. The method had a very broad scope as it applies to both aliphatic and aromatic aldehydes and hydroxylamines, to a variety of cyclic yne-enones, and to yne-enone-derived oximes. DFT calculations complement this study to enlighten reactivity issues and mechanistic pathways. The experimental part of the paper was very detailed, including the reaction process of 2-(Benzyloxy)acetaldehyde(cas: 60656-87-3Category: ethers-buliding-blocks)
2-(Benzyloxy)acetaldehyde(cas: 60656-87-3) may be used in the following syntheses: (3S,5S)-methyl 6-benzyloxy-3,5-dihydroxyhexanoate ,(S)-5-benzyloxy-4-hydroxypentan-2-one, myxothiazols.Category: ethers-buliding-blocks
