A novel and efficient one-pot synthesis of tetrazole -derivatives such as Irbesartan and its analogues has been described from the primary acid amide derivatives. Thus 2-alkyl-3-[ P-( O-amidophenyl)benzyl]-1,3-diazaspiro[4.4]non-1-en-4-one derivative

A simple one pot synthetic method for the isomerization of cephem double bond from the natural 3-position to 2-cephem positions is affected by silylation. Thus cephalosporin acids are treated with Ntrimethylsilylacetamide (MSA) or N,O-bis(trimethylsi
