An advantageous synthesis of 5,6,7,8-tetra-hydrotetrazolo[1,5- a]pyridines
Vonhoff, Stefan,Vasella, Andrea
, p. 551 - 560 (2007/10/03)
The one-step synthesis of various O-benzyl-protected glyconotetrazoles from the corresponding glyconolactams is reported. The method is superior to the previously employed cycloaddition of azidonitriles as it uses readily available starting materials and leads to higher yields.
