Parallel Synthesis of 1,6-Disubstituted-1,2,4-triazin-3-ones on Solid-Phase
摘要:
A parallel solid-phase synthesis of 1,6-disubstituted-1,2,4-triazin-3-one from MBHA resin is described. The reduction of resin-bound nitrosamino acids provides hydrazines efficiently without affecting the amide bond. The trityl protected hydrazine is then reduced with borane, and cyclized with 1,1-carbonyldiimidazole. The desired products are cleaved from their solid support and obtained in good yield and purity. This methodology is of value for the rapid parallel preparation of these potentially bioactive molecules.

An efficient approach for the solid-phase synthesis of 2,3,5,6-tetrahydro-1H-imidazo[1,2-a]benzo[d][1,3]diazepines has been developed. It was realized by Pd(OAc)2/Cu(OAc)2-cocatalyzed intramolecular aryl guanidinylation. solid-phase synthesis - 1,3-benzodiazepines - Pd(OAc)2/Cu(OAc)2 - cyclization - guanidinylation
