(2,2-dichloro-3-oxocyclobutyl) 2,2-dimethylpropanoate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a stirred suspension of zinc dust (103 g, 1568 mmol) in HOAc (200 ml) was added a solution of 2,2-dichloro-3-oxocyclobutyl pivalate (75 g, 314 mmol) in HOAc (400 ml) dropwise in an ice bath. The reaction mixture was stirred for 1 h, filtered the solid through celite and washed with DCM. The DCM layer was washed with H2O, NaHCO3, brine, dried over MgSO4, filtered and concentrated. The crude material was purified by ISCO (10% EtOAc/Hexanes) to give the title compound as a light yellow oil. filtered the solid through celite washed with DCM The DCM layer was washed with H2O, NaHCO3, brine dried over MgSO4 filtered concentrated The crude material was purified by ISCO (10% EtOAc/Hexanes)

Conditions: temp:22.51; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a stirred mixture of vinyl pivalate (30 g, 234 mmol) and zinc (31 g, 468 mmol) in ether (300 ml) was added a solution of 2,2,2-trichloroacetyl chloride (55 g, 304 mmol) in ether (300 ml) dropwise (2-3 h) in a water bath. (Note: fast addition causes the reaction temp. to elevate) while maintaining the reaction temperature between 15-30° C. After the reaction was done (stained with KMnO4 solution), it was filtered through Celite. The filtrate was washed with cold water, brine, dried over MgSO4 and concentrated to give the title compound as an orange solid. (Note: fast addition the reaction temp was filtered through Celite The filtrate was washed with cold water, brine dried over MgSO4 concentrated
