摘要
An efficient strategy for introducing a nitrogen atom in positions 3 and 11 of the steroidal skeleton, which are key positions for biological purposes, is described. This procedure involves an intramolecular Diels-Alder cycloaddition of o-quinodimethanes which are generated from a 3-azabicyclo[4.2.0]octa-1,3,5-trien-7-one. The characteristic H-1 and C-13 NMR spectroscopic features of the synthesized compounds are reported. (C) 2011 Elsevier Inc. All rights reserved.
