2-Ethoxy-2-methylpropanoic acid → HCID 67730991, compound

Participants

Reaction Steps

A procedure similar to that described in Example 10, above, was followed, but using 1.15 g of 2-ethoxy-2-methylpropionic acid and 1.0 g of (4R,6R)-6-{(1S,2S,6S,8S,8aR)-2-[1,2,6,7,8,8a-hexahydro-6-t-butyldimethylsilyloxy-8-hydroxy-2-methyl-1-naphthyl]ethyl}tetrahydro-4-t-butyldimethylsilyloxy-2H-pyran-2-one [prepared as described in Example B, above], to give 414 mg of a fraction containing the title compound. This fraction was usedin the next step without further purification.
