Yield:-
Reaction Conditions:
with pyridinium chlorochromate in ethanol;hexane
Steps:
2 Step 2:
Step 2: 2,6-Dimethyltetrahydropyran-4-one A solution of 2,6-dimethyl-γ-pyrone (17 g, Aldrich) in EtOH 95% (300 mL) was hydrogenated for 3 days under 70 psi. After filtration over celite, the solvent was evaporated and replaced by CH2 Cl2. The solution was then treated with celite (30 g) and PCC (48.5 g). The suspension was stirred for 3 hr. and the reaction was diluted with Et2 O (300 mL) and then filtered over a pad of celite. The filtrate was evaporated to dryness and the residual solution was then chromatographed using hexane/Et2 O (1:1) to give the title compound.
