Purines. LIX. An alternative synthesis of 7-alkyl-1-methyladenines by regioselective alkylation, fission, and reclosure of the adenine ring
Fujii,Saito,Suzuki,Kunugi
, p. 151 - 153 (1994)
7-Alkyl-1-methyladenines (12a,b) have been synthesized from 1-alkyl-4- aminoimidazole-5-carboxamides (5a,b) in two steps [hence from adenine (1) in six steps]. The synthesis started with dehydration (using POCl3-HCONMe2) of 5a,b, rea

The present invention relates to bicyclic heterocyclic derivatives of Forrmula (I), to the process for preparing such compounds and to their use in the treatment of a pathological condition or disease susceptible to amelioration by TRPA1 channel inhibition or antagonism.
Purines. LXXV. Dimroth rearrangement, hydrolytic deamination, and pyrimidine-ring breakdown of 7-alkylated 1-alkoxyadenines: N(1)-C(2) versus N(1)-C(6) bond fission
Itaya, Taisuke,Ito, Nobuaki,Kanai, Tae,Fujii, Tozo
, p. 832 - 841 (2007/10/03)
On treatment with boiling H2O for 5-6h, 1-alkoxy-7-alkyladenines (13) underwent hydrolytic cleavage of the N(1)-C(2) and the N(1)-C(6) bonds to produce the imidazole-5-carboxamidines (14) in 53-60% yields and the imidazole-5-carboxamides (18) i
