## Abstract The synthesis of the novel boron‐containing nucleobase 2‐benzyl‐1,4‐dihydro‐1‐hydroxythieno[3,2‐__c__]‐[1,5,2]diazaborin‐3(2__H__)‐one (8), a thieno‐fused 4‐borauracil, is described. Compound 8 was prepared in three steps starting from 2‐thiophenecarbonyl chloride (4). A multinuclear an
## Abstract magnified image One‐pot reaction of 3‐aryl‐5‐methyl‐1,3,4‐oxadiazolin‐2‐ones **1a‐g** with ethanolamine yielded the 4‐(2‐hydroxyethyl)‐2‐aryl‐5‐methyl‐2,4‐dihydro‐3__H__‐1,2,4‐triazolin‐3‐ones **2a‐g** which were converted to the azido compounds **6a‐g**. These azides on 1,3‐dipolar cy
