Unprecedented reaction of a thiocarbonyl ylide with carbonyl compounds: a novel synthesis of 1,3-oxathiolanes
Abstract
Thioformylium methylide, readily generated from chloromethyl trimethylsilylmethyl sulphide with the aid of fluoride ion, reacts with carbonyl compounds such as aldehydes, α-diketones, and α-oxo amides to give the corresponding 1,3-oxathiolanes in good yields.
