Synthesis and crystal structure of 5-amino-4,6-dicyano-3-dicyanomethylene-1, 8,8-trimethyl-2-azabicyclo[2.2.2]oct-5-ene
摘要:
5-Amino-4,6-dicyano-3-dicyanomethylene-1,8,8-trimethyl-2-azabicyclo[2.2.2]oct-5-ene has been synthesized. The molecular and crystal structure of this compound has been determined.
by variously pretreated alumina (1/4 equiv based on the amount of KF) to give a 2-azabicyclo[2.2.2]octanederivative in water (in more than 90% yield). With more catalyst (1 equiv), a potassium salt of the product was formed unexpectedly. Both products released isobutylene to give the corresponding pyridine derivatives.
