PROCEDURE

实验过程

A mixture of 4-nitrobenzyl 2-diazo-4-[(2R, 3S)-3-(1-methoxy-1-methylethyl)-4-oxo-azetidin-2-yl]-3-oxobutanoate (56.5 mg) and a catalytic amount of rhodium (II) acetate (ca. 1 mg) in dry benzene (5.6 ml) was refluxed for 30 minutes. After cooling to ambient temperature, the mixture was filtered and evaporated in vacuo to give 4-nitrobenzyl (2R, 5R, 6S)-3,7-dioxo-6-(1-methoxy-1-methylethyl)-1-azabicyclo[3.2.0]-heptane-2-carboxylate (50.0 mg) as an amorphous solid.
