N,N-dimethylchlorosulfitemethaniminium chloride as a cyclodehydrating agent: An efficient one-pot preparation of 4-methyl-2-phenyl-Δ2-oxazolin-5-one and its reactions with various imines and bis-imines

N,N-Dimethylchlorosulfitemethaniminium chloride prepared from thionylchloride and dimethylformamide in dry benzene at ambient temperature was found to be an efficient and mild cyclodehydrating agent of N-benzoyl amino acids for the synthesis of various β-

MESO-IONIC OXAZOLONES IN HETEROCYCLIC SYNTHESIS: REACTION OF 4-METHYL-2-PHENYL-Δ2-OXAZOLIN-5-ONE WITH ALDAZINES

Reaction of 4-methyl-2-phenyl-Δ2-oxazolin-5-one (2) with various aldazines (1) yielded pyridazinones (3) in good yields.Their structures were fully supported by spectral data.
