Synthesis of Calycotomine and N-Methylcalycotomine Using a Petasis Reaction — Pomeranz-Fritsch-Bobbitt Cyclization Sequence
摘要:
The use of aminoacetaldehyde acetals as the amine components in the one-step, three-component Petasis reaction followed by the Pomeranz-Fritsch-Bobbitt cyclization has been shown to be a convenient and simple method for the synthesis of tetrahydroisoquinoline alkaloids. Using this method two alkaloids, calycotomine and N-methylcalycotomine hydrochlorides, have been prepared in 61% overall yield.
