Intramolecularamidomercuration of N-methoxycarbonyl-6-aminohept-1-ene and reaction of the resulting organomercurial with sodium borohydride in the presence of acrylonitrile or decen-3-one has been used to prepare trans-2,6-dialkylpiperidines, including solenopsin A, a constituent of the venom of the fire-ant.
N-甲氧基羰基-6-氨基庚-1-烯的分子内酰胺化反应以及所得有机汞与硼氢化钠在丙烯腈或癸烯-3-酮的存在下的反应已用于制备反式-2,6-二烷基哌啶,包括slenopsin A ,是火蚁毒液的成分。

Upon photolysis in methylene chloride at −78 °C, different N-chlorolactams underwent a novelringcontraction to the corresponding carbamoyl chlorides, which were converted to the methyl carbamates. The rearrangement is 100% stereoselective, occurring with retention of configuration at the migrating carbon center. The yields of isolated carbamates ranged from 40% to 57%, the other product being the
