  Reduction of cyclopropylmethylamines proceeded under mild reaction conditions in the presence of platinum (IV) oxide catalyst and hydrobromic acid at rt, providing isobutylamines and no linear butylamines. The ring cleavage reaction was widely applicable to cyclopropane rings in various compounds such as N-cyclopropylalkyl, O-cyclopropylalkyl, and C-cyclopropylalkyl derivatives. Although unactivated

  在室温下，在氧化铂（IV）催化剂和氢溴酸存在下，在温和的反应条件下进行环丙基甲胺的还原，得到异丁胺，而没有线性丁胺。所述环裂解反应广泛适用于各种化合物如N-环丙基烷基，O-环丙基烷基和C-环丙基烷基衍生物中的环丙烷环。尽管未活化的环丙烷环也被裂解，但是环丁烷环在相同的反应条件下是可容忍的。

  Selective ring opening reaction of the N-cyclopropylmethyl group in naltrexone (1d) was effected in the presence of platinum (IV) oxide and hydrobromic acid under a hydrogen atmosphere at rt to selectively afford N-isobutyl derivative 10. The binding affinity of N-i-Bu derivative 10 for opioid receptors was 11 17 times less than that of the corresponding N-CPM compound, naltrexone (1d). However, compound 10 showed dose-dependent analgesic effects. Contrary to expectations based on previous structure-activity relationship studies for a series of N-substituted naltrexone derivatives that compound 10 would be an opioid antagonist, 10 showed dose-dependent analgesia in the mouse acetic acid writhing test (ED50: 5.05 mg/kg, sc), indicating it was an opioid agonist. This finding may have a great influence on the drug design of opioid agonists. (C) 2008 Elsevier Ltd. All rights reserved.
