    • Typical Experimental Procedure A mixture of an aldehyde (1.0 mmol) and an appropriate 2-amino alcohol (1.0 mmol) was stirred for 4 h at r.t, Diacetoxyiodo)benzene (1.2 mmol) was then added to the above mixture and the resulting reaction mixture was again subjected for stirring for another 3-6 h. The progress of the reaction was monitored by TLC. After the completion of the reaction, H2O (15 mL) was added and the mixture extracted with CH2Cl2 (2 x 15 mL, The combined organic extracts were dried over anhyd Na2SO4, concentrated in vacuo, and chromatographed to give 2-substituted oxazolines/oxazines.
