Processes for the preparation of substituted propenone derivatives

   
   

Industrial and commercial processes for the preparation of 2-acyl-5-benzylfuran derivatives, 1,2,4-triazole-3-carboxylic acid ester derivatives or propenone derivatives having an anti-HIV activity; and useful crystals of the derivatives. A deblocking: (III-2), (IV-10), (VI-1), wherein R.sup.1, R.sup.2 and R.sup.4 are each independently hydrogen or the like; A is CR.sup.6 or N; R.sup.6 is hydrogen or the like; Q is a protecting group; and L is a leaving group.
