The invention discloses a preparation method of 2-trifluoromethyl-1-carbobenzoxy-1-aza-cyclane, and mainly solves the problems that the step of the preparation of alpha-position trifluoromethyl aza-cyclane is long, the yield is low, and the like. The meth

The use of enol phosphinates as electrophiles for cross-coupling reactions has been explored. Both boronic acids (Suzuki-Miyaura reaction) and stannanes (Stille reaction) couple efficiently with lactam derived phosphinates. The 2008 Royal Society of Chemi

The asymmetric formation of azaspiro[5.6]dodec-9-ene system is described. The Diels-Alder reactions of an α-methylene caprolactam and diene in the presence of a Cu(II) and (S,S)-tBu-BOX complex afford the desired spirocyclic compounds with good exo-selectivity as well as excellent enantioselectivity. These exo-adducts would be applicable to the synthesis of marine natural toxins including the corresponding cyclic imine moiety.
