Azido nucleosides couple with phosphoramidites via an initial iminophosphorane, which eliminates acrylonitrile to generate the coupled dimer P(V) product. The vulnerable phosphite triester intermediate is bypassed entirely, making the methodology ver

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.
