HCID 54518938, compound → Ethyl (2R)-2,3-dihydroxy-2-methylpropanoate

Participants

Reaction Steps

22 g of ethyl (R)-2-benzyloxy-3-hydroxy-2-methyl-propionate (manufactured in accordance with Example 1) in 150 ml of ethyl acetate were hydrogenated with hydrogen gas in the presence of 11 g of 5% by weight palladium/carbon catalyst up to the cessation of the hydrogen uptake. The catalyst was filtered off, washed with ethyl acetate (2×50 ml), the filtrate was concentrated in the vacuum and the residual oil was distilled at 56°-57°/0.1 mmHg. There were obtained 12.7 g of ethyl (R)-2,3-dihydroxy-2-methyl-propionate in the form of a colorless viscous liquid. [α]D =+0.339° (undiluted);=+11.6° (c=2.12 in chloroform).
