The best way to measure whole body production of the locally acting hormone prostaglandin E2 (PGE2) is to assess the accumulation of the major urinary metabolite, PGE2UM. A practical preparation of this delicate diacid is described. This synthetic PGE2UM will enable production of the antibodies that will be used to quantify this key metabolite.
测量局部作用激素前列腺素 E 2 (PGE 2 )的全身产生量的最佳方法是评估主要尿液代谢物 PGE 2 U M的积累。描述了这种精致二酸的实际制备方法。这种合成的 PGE 2 U M将能够生产用于量化这种关键代谢物的抗体。

alpha-diazoketones react with allylic alcohols in the presence of Rh(II) catalysts to furnish intermediate enols which subsequently undergo Claisen rearrangement to alpha-hydroxyketones. Herein we report (1) studies into the mechanism of this transformation which establish that Claisen rearrangement is neither rhodium- nor acid-catalyzed but a reaction intrinsic to the intermediate enols that proceeds at a rate
