Page/Page column 9-10, (2008/06/13)
The present invention is to provide a process for preparing an alkyl 3-(4-tetrahydropyranyl)-3-oxopropanoate compound represented by the formula (1): wherein R1 and R2 may be the same or different from each other, and represent a group which does not participate in the reaction, and R1 and R2 may be bonded to form a ring, and the ring may contain a hetero atom(s), and R3 represents a hydrocarbon group, which comprises reacting 4-acyltetrahydropyran represented by the formula (2): wherein R1 and R2 have the same meanings as defined above, and a carbonic acid diester represented by the formula (3): wherein R3 has the same meanings as defined above, and two R3s may be bonded to each other to form a ring, in the presence of a base, and a process for preparing 4-acyltetrahydropyran.
