RESUMO
It was found that 4-hydroxy-2-butenoic ester (11) could not react with 3,4-dihydro-isoquinoline (4a). Individual addition reactions of γ-mercapto-α,ß-unsaturated esters (18) and -unsaturated amide (19) with 3,4-dihydroisoquinolines (4) were carried out under appropriate conditions to provide the corresponding thiazolo[2,3-α]isoquinoline derivatives with good yields (up to 87%) and significant diastereomeric selectivity. The mechanism of the crucial reaction was discussed.
