Lithiation of N-6-(alpha-haloacyl)-3-isopropylsydnone imines at 4-position followed by treatment with sulfur affords the 4-lithiosulfanyl derivatives whose intramolecular cyclization leads to [4,5]-bicyclic sydnone imines.

N6-phosphorylated sydnone imines based on the reaction of sydnone imine hydrochlorides with substituted phosphinate or phosphonate acids chlorides in the presence of a base was elaborated. A possibility of straight deprotonation of sydnone imines with n-BuLi followed by the reaction 4-Li-derivatives thus obtained with electrophiles was demonstrated. Novel representatives of bicyclic sydnone imines fused
