Paragraph 00030; 00032-00033, (2022/01/24)
The present disclosure pertains to new methods of performing a hydrodealkenylation of monounsaturated alcohols, thiols, and derivatives thereof, such as terpenes and derivatives, comprising ozonolysis and quenching using a sulfinic acid or sulfinic acid salt.

4-Hydroxy-6-methyl-2-pyrone (triacetic acid lactone) (1) is efficiently alkylated at C-3 with primary and secondary allylic substrates under thermodynamic control by using palladium(0) catalysts.Controlled hydrogenation of the resulting allylated derivatives affords pyrones with saturated chains at C-3.Allylic alkylations occur with retention of configuration at the allylic center, probably through a reversible kinetically favored O-alkylation.
