A new efficient method for the synthesis of 3,4-dihydro-2H-1,4-benzoxazines via iodocyclization
摘要:
An efficient approach for the synthesis of 3,4-dihydro-2H-1,4-benzoxazine derivatives is described by molecular iodine- mediated cyclization. The reaction condition is very simple, offers easy isolation, and affords good to excellent yields of the products. (C) 2010 Elsevier Ltd. All Fights reserved.
