Applicazioni

2,6-Difluorobenzaldehyde can be used as a reactant to synthesize:
  • 5-Cyano-6-(2,6-difluorophenyl)-5,6-dihydro-2-thiouracil via one-pot cyclocondensation reaction with ethyl cyanoacetate and thiourea.
  • 1-(2,6-Difluorobenzyl)-2-(2,6-difluorophenyl)-benzimidazole by reacting with 1,2-phenylenediamine in the presence of a catalytic amount of p-toluenesulfonic acid.
  • (3E)-4-(2,6-Difluorophenyl)-3-buten-2-one by Wittig olefination reaction with acetylmethylidenetriphenyl phosphorane.
  • Methyl 4-fluorobenzo[b]thiophene-2-carboxylate by treating with methyl thioglycolate in the presence of K2CO3.

We describe a technique for transferring electrophoretically separated bands of double-stranded DNA from agarose gels to diazobenzyloxymethyl-paper. Controlled cleavage of the DNA in situ by sequential treatment with dilute acid, which causes partial depurination, and dilute alkali, which causes cleavage
