Technical Notes:
1.Catalytic as ymmetric homo- 1 ,3 -dipolar cycload ditions of azomethine ylides: diastereo and enantios elective s ynthesis ofimidazolidines
2.Enantios elective construction of the biologically significant dibenzo1 , 4diazepine scaffold via organocatalytic as ymmetric three component reactions
3.Enantios elective construction of the biologically important cyclopenta1 , 4diazepine framework enabled by asymmetric catalysis by chiral spiro-phos phoric acid.
4.Triply hydrogen- bond- directed enantioselective ass embly of pyrrolobenzo-1 ,4-diazine skeletons with quaternary stereocenters.
