Abstract

2-Metallo-2-nitropropanes have been successfully used for the cyclopropanation of electrophilic alkenes and act as i so p ro py I id en e transfer reagents. ... Cyclopropanecarboxylic esters play an important role in organic synthesis .2 The gem-dimethylcyclopropanecarboxylic acid unit is also found in pyrethroids, an important class of insecticide.3.4 We have already described several syntheses of such derivatives,5.6 most involving as the key step the construction ...
