<p>Disclosed is a process for production of a compound represented by the formula (11):
[wherein P 1 represents a hydrogen atom or a protective group for a hydroxyl group; P 7 represents a hydrogen atom or a protective group for a hydroxyl group; P 8 represents a hydrogen atom, an acetyl group or a protective group for a hydroxyl group and P 9 represents a hydrogen atom or a protective group for a hydroxyl group, or P 8 and P 9 may together form a group represented by the formula:
(where R 5 represetns a phenyl group which may have a halogen atom; and R 1 represetns a hydrogen atom or a hydroxyl group)]. The process comprises the step of reacting a compound represented by the formula (12):
(wherein P 7 and R 1 are as defined above) with a compound represented by the formula (13):
(wherein P 1 , P 8 , P 9 and R 5 are as defined above) in the presence of a catalyst.</p> |
