Reaktionen von 4,4-Bis(trifluormethyl)-1,3-diazabuta-1,3-dienen. Synthese trifluormethyl-substituierter Heterocyclenvia Baylis-Hillman-Reaktion
摘要:
4,4-Bis(trifluoromethyl)-1,3-diazabuta-1,3-dienes and alpha,beta-unsaturated heteromultiple bond systems react to give bis(trifluoromethyl) substituted heterocycles. The first step of the formal [4 + 2] cycloaddition represents a Baylis-Hillman reaction.
