  摘要：

  中性离子1, 3-噁唑鎓-5-醇盐（munchnones）在C-4取代基为芳香族时，与氧反应相对迅速，生成自氧化产物。自氧化发生在由N-酰基四氢异喹啉-1-羧酸或四氢-β-卡比啉-1-羧酸生成的munchnones中。通过18O标记实验阐明了机制，涉及一系列已知的自氧化过程，包括氧化、产物过氧阴离子的环化和氧化断裂。

  silica and (1R,2R)-bis(dimethylamino)cyclohexane (3) were obtained. This reaction was exploited to propose a new route for the methylation of amines. Such methylation reaction of amines could be extended to other amines and provides a new method for the selective monomethylation of primary amines. (© Wiley-VCH Verlag GmbH & Co.

  The cyclopeptide alkaloid, named condaline-A, was isolated from the root bark of Condalia buxifolia Reissek (Rhamnaceae), along with the known compounds adouetine-Y', scutianine-B, and scutianine-C. Their structures were determined by spectroscopic analyses, with their antibacterial activities being evaluated by use of a direct bioautography method.

  环肽生物碱，命名为 condaline-A，是从 Condalia buxifolia Reissek（鼠李科）的根皮以及已知化合物 adouetine-Y'、scutianine-B 和 scutianine-C 中分离出来的。它们的结构是通过光谱分析确定的，它们的抗菌活性是通过使用直接生物自显影方法来评估的。

  DOI：10.1055/s-2005-863735

  日期：——

  A range of α-amino esters can be turned into sulfonyl­hydantoins 2 in a single, atom-economic step using sulfamide and DBU. This procedure obviates the need for a three- or four-step sequence utilised by traditional procedures. Two new six-membered analogues 3 and 4 have also been prepared utilising novel synthetic protocols.
