Tetrazole or urea compound: The thermolytical decomposition under microwave irradiation of diazidated malonamides was studied. A variety of different tetrazoles could be synthesized in three steps starting from diethyl malonate. Furthermore, the formation of isocyanates in situ was investigated.
A new practical method for the synthesis of unsymmetrical ureas via high-pressure-promoted condensation of 2,2,2-trichloroethyl carbamates (Troc-carbamates) with amines
A new practical method for the synthesis of unsymmetrical ureas was achieved by condensation between 2,2,2-trichloroethyl carbamates (Troc-carbamates) and primary or secondary amines under high-pressure conditions. (c) 2005 Elsevier Ltd. All rights reserved.

(SPECT) or positron emission tomography (PET) with appropriate radioligands, offer the possibility of assessing beta-adrenoceptor density non-invasively in humans. To date, neither a SPECT nor a PETradioligand is available for the selective imaging of cardiac beta(1)-ARs. The aim of this study was to develop potential high affinity beta(1)-selective AR radioligands for the non-invasive in vivo imaging
