- Production method for diazabicyclooctane derivative and intermediary body thereof
-
The present invention provides a production method for a diazabicyclooctane derivative expressed by formula (IV), and an intermediary body thereof (in the formula: P is an acid-removable NH protective group; R1 represents a 2, 5-dioxopyrrolidine-1-yl, a 1, 3-dioxo-3a, a 4, 7, 7a-tetrahydro-1H-isoindole-2(3H)-yl, a 1, 3-dioxohexahydro-1H-isoindole-2(3H)-yl, or a 3, 5-dioxo-4-azatricyclo[5.2.1.02, 6]deca-8-en-4-yl; R2 represents hydrogen, C1CO-, or C13COCO-, R3 represents a C1-6 alkyl or a heterocyclyl, or joins with a bonded -O-NH- to form a 3-7 member heterocyclyl ring; and OBn represents a benzyloxy).
