Synthesis of benzofuroquinolizine for α-2 adrenoceptor antagonist MK-912: an O-analogue of the Pictet-Spengler reaction
摘要:
Efficient synthesis of benzofuroquinolizine ketone 1 was accomplished in four steps from ethyl 3-benzofuranacetate. The O-analogue of the Pictet-Spengler cyclization was used to form the benzofuroquinolizine ring structure as a key step. (C) 1999 Elsevier Science Ltd. All rights reserved.
