“…Abdelhaim e colaboradores 7 descreveram a obtenção dos heterociclos benzoxazol (X=O) 63 e benzoimidazol (X=NH) 64 através Thomas e Asokan 38 desenvolveram em 2002, a partir de α-oxoceteno ditioacetais, a síntese de 4-aril-2-tiometilpiridinas 70 tendo como precursor as 4,4-ditiometil-1-aril-3-propen-1-onas 67 (Esquema 27). O intermediário α-hidroxiceteno ditiometilacetal 68 é sintetizado a partir da reação de adição à carbonila do composto 67 com o reagente de Grignard (preparado in situ com iodeto de metila e magnésio).…”

“…Heterocyclic ketene aminals are powerful and versatile intermediates in heterocyclic synthesis.Reactions of cyclic methylidene-aminals with anumber of electrophilic reagents have been successfully used to synthesize five-and six-membered and fused heterocycles in recent years.These fused heterocyclic structures are frequently found in pharmacophores and play important roles in drug discovery.T hey are also used as pesticides,h erbicides [4], antileishmanial agents [5], antianxiety agents [6], and antibacterial drugs [7].…”
