Similarly, methoxymethylene cyanimide (159) or its ethoxymethylene analogues (Scheme 57) are widely utilized for the synthesis of various aza[3.3.3]cyclazine derivatives.[149,150,153,154,157] Compound 152 was also synthesized via 160 from 159 and 158 in manner similar to that described for the preparation of 155 (Scheme 56).[184,185]
