✦ Synopsis

In the presence of LiNTf 2 , epoxides undergo ring opening with high regioselectivity and in good yield when they are treated with nucleophiles such as amines, hydrazines and thiophenol.

The regioselectivity of nucleophilic ring opening of some 3,4-epoxy and 3,4-aziridino alcohols has been studied. The nucleophiles chosen were complex hydrides (LiAIH4, Red-Al and DIBAL) and Lipshutz-or Gilman-type organocuprate reagents. The C-4 substituent in the substrates was varied in order to s
