Taking into account the pharmacological properties exhibited by aporphinoids, several synthetic approaches have been reported allowing access to aporphine cores.8, 9, 10 and 11 The most widespread approaches are those based on biosynthetic routes, having in common the formation of the C ring, employing 1-benzyltetrahydroisoquinoline intermediates,8, 9 and 10 which are well exemplified by the Pschorr reaction.8 In addition, over the last decades, approaches based on benzyne chemistry, involving reactions between 1-methyleneisoquinolines and arenediazonium-2-carboxylates, which provide dehydroaporphines in moderate yields, have experienced a remarkable development.11 However, the formation of dehydroaporphines can be pointed as a negative aspect related with the use of arynes to synthesize aporphinoids, once the reduction of dehydroaporphines to aporphines is not a well-documented transformation and the procedures reported in the literature involve expensive metal9d or harsh conditions.9e Moreover, some researchers have discouraged the use of arenediazonium-2-carboxylates for safety reasons.11a In this context, our research group has explored an approach that employs reactions between isoquinoline derivatives and silylaryl triflates in the presence of CsF, providing aporphine cores instead of dehydroaporphines, under mild reaction conditions, through [4+2] cycloaddition reactions followed by hydrogen migrations,12 in total syntheses of aporphine alkaloids (Fig. 1).
