Abstract
The present invention is directed to a process for preparing a compound having the formula: wherein R is a range of organic groups and X is a leaving group. The process may include reacting a compound of the formula with a water-removing reagent. Also, when X is a halogen, the process may include reacting a compound of the formula with a halogenating agent or a sulfonylating agent. Alternatively, when X is a halogen, the process may be carried out by reacting a compound of the formula IV where Rand Rare defined organic groups with a compound of the formula halogen-C(—O)—O—C1 -C8alkyl, halogen-C(—O)—O-aryl or halogen-C(—O)—O-benzyl.
