    摘要: An object of the present invention is to provide a tread centering device which automatically detects the position of tread center and holds it in a straight form even when the center of tread is not positioned in a straight form. The device mainly comprises a plurality of detectors for detecting a groove for centering the tread, a holding plate which is inserted into the detected groove, and a mechanism which moves said holding plate transversely to align said groove in a straight form.

    摘要: A process for preparing 7-benzylpurine derivatives is provided. An acetylpurine nucleoside is reacted with a benzyl halide to benzylate the 7-position of the purine base, and an acid is then added to the reaction mixture to hydrolyze the glycoside bond. The 7-benzylpurines may be used to prepare 9-substituted purine derivatives. Specifically, a process for producing a 7-benzylpurine compound of Formula (5):

    摘要: Purine derivatives in which a desired substituent is introduced into the 9-position only are synthesized by first introducing an easily-removable substituent in the 7-position of a purine base of natural purine nucleosides obtained through fermentation or derivatives thereof, then hydrolyzing the ribose moiety to form purine derivatives having the substituent in the 7-position, subsequently introducing the desired substituent in the 9-position, and then removing the substituent in the 7-position.
