PURPOSE:To obtain a new compound useful as an agricultural germicide. CONSTITUTION:A compound of formula I (Z is hydroxyl group-protecting group for benzyl, benzoyl, acetyl group, etc.), e.g. (7R,8S,9S-10R)-8,9,10-tribenzyloxy-7- benzyloxymethyl-6-oxa-1,5pentamethylene tetrazole. This compound of formula I can be obtained by dissolving a compound of formula II in an inert solvent such as benzene or toluene followed by either heating or irradiation using e.g. a mercury-vapor lamp. The compound of formula II can be obtained by reaction of a compound of formula III with an azidating agent (e.g. trimethylsilyl azide) in the presence of a Lewis acid (e.g. anhydrous aluminum chloride) in a solvent (e.g. dichloromethane). |
