Transesterification of trimethyl orthoacetate: an efficient protocol for the synthesis of 4-alkoxy-2-aminothiophene-3-carbonitriles
摘要:
A facile one-pot method is reported for the synthesis of 4-alkoxy-2-aminothiophene-3-carbonitriles. Transesterification of trimethylorthoacetate technique allowed introducing alkoxy substituents into 2-aminothiophene ring system. Diverse alkoxy substituents could be introduced efficiently by using this methodology. Further the synthesis of some of new 4-alkylamino-2-aminothiophenes is also reported. (C) 2012 Elsevier Ltd.

A method of producing a metal phthalocyanine compound, which contains: conducting a reaction between at least two compounds selected from among Compounds A to F of formula (I), and a metal compound, in a buffer solution of an organic base or an inorganic base and an acid, in the presence of a dehydrating agent:
wherein R is a hydrogen atom or a substituent; 1 is an integer of 0 to 4; a plurality of Rs may be the same or different from each other when 1 is 2 to 4; and G is a group of atoms necessary for forming at least one of a 5- or 6-membered aromatic ring and a 5- or 6-membered hetero ring.
