Uses

(4aS,8aS,9S)-3-(Benzyloxy)-4a-((tert-butyldimethylsilyl)oxy)-9-(dimethylamino)-8a,9-dihydronaphtho[2,3-d]isoxazole-4,5(4aH,8H)-dione serves as a highly versatile intermediate for the construction of diverse tetracycline antibiotics.

Uses

(4aS,8aS,9S)-3-(Benzyloxy)-4a-((tert-butyldimethylsilyl)oxy)-9-(dimethylamino)-8a,9-dihydronaphtho[2,3-d]isoxazole-4,5(4aH,8H)-dione serves as a highlyversatile intermediate for the construction of diverse tetracycline antibiotics.

Synthesis

852821-06-8

2,6-Dimethylpyridine (75.0 μL, 0.640 mmol, 5.0 eq.) and tert-butyldimethylsilyl trifluoromethanesulfonate (88.0 μL, 0.380 mmol, 3.0 eq.) were sequentially added to a solution of (4AS,8aS,9S)-3-(phenylmethoxy)-9-(dimethylamino)-8a,9-dihydronaphtho[2,3-d]isoxazole-4. 5(4aH,8H)-dione (47.0 mg, 0.130 mmol, 1.0 equiv) in a solution of dichloromethane (3 mL). The reaction mixture was stirred at 23 °C for 3 hours. Subsequently, it was quenched by addition of aqueous potassium phosphate buffer solution (pH 7.0, 0.2 M, 15 mL). The reaction mixture was extracted with dichloromethane (2 x 20 mL), the organic phases were combined and dried over anhydrous sodium sulfate. The dried organic phase was filtered and the filtrate was concentrated to give (4AS,8aS,9S)-3-(benzyloxy)-4a-((tert-butyldimethylsilyl)oxy)-9-(dimethylamino)-8a,9-dihydronaphthaleno[2,3-d]isoxazole-4,5(4aH,8H)-dione (56.0 mg, 91% yield) as a white crystalline solid.
