Abstract
The 1β:β1 intermediates generated by addition of isoquinoline to isocyanates were trapped by diphenyl phosphonate to yield diphenyl [2β(aminocarbonyl)β1,2βdihydroisoquinolinβ1βyl]phosphonates in good yields under solventβfree conditions.

Several (2-amino-4H-1-benzopyran-4-yl)phosphonates were efficiently synthesized by employing a multicomponent protocol involving a salicylaldehyde, malononitrile or ethyl cyanoacetate, and a trialkyl phosphite in polyethylene glycol. The latter could be recovered and re-used. No additional solvent o
