Sodium Carbonate → (1S,3S,4S)-3-[(benzyloxy)methyl]-4-{[tert-butyl(dimethyl)silyl]oxy}cyclopentanol

Participants

Reaction Steps

A suspension of (1R,4S)-3-[(benzyloxy)methyl]-4-{[tert-butyl(dimethyl)silyl]-oxy}cyclopent-2-en-1-ol (7.54 g, 0.0225 mol) (Ruediger, E; Martel, A; Meanwell, N; Solomon, C; Turmel, B. Tetrahedron Lett. 2004, 45, 739-742), sodium carbonate (5.7 g, 0.054 mol) and 10% Pd/C (2 g, 0.002 mol) in EtOAc (90 mL) was stirred under an atmosphere of hydrogen for three hours. The reaction flask was purged with nitrogen and the mixture was filtered through celite with EtOAc. The filtrate was concentrated to obtain 7.16 g (76%) of the title compound as a 4:1 mixture of diastereomers (desired:undesired).
