Synthesis Of 1, 3-oxathiolanes Without Use Of Organic ‎solvent At Room Temperature. Remarkable Functional ‎selectivity



Authors : Dokari H . Hammadi M . Benferrah‎ N . Villemin‎ D .

Abstract

The aluminosilicates acids are efficient catalysts for the synthesis ‎of oxathiolanes without solvent at room temperature. A functional ‎selectivity was observed between aldehydes and ketones, ‎aldehydes were transformed quantitatively. A functional selectivity ‎has not been described before, it was observed within differents ‎aldehydes or within differents ketones. This selectivity is important ‎for the control of the reactions (activation or protection) of ‎carbonyl compounds in organic synthesis. ‎
