โœฆ Synopsis

The stereoselective synthetic methods for anti-and syn-fused tricyclic guanidine compounds 4a and 4b were developed based on a successive 1,3-dipolar cycloaddition. Through these synthetic studies, the stereochemistry of the left-hand tricyclic guanidine unit of batzelladine F (3) was confirmed as a syn-fused one, which is identical with the structure reported by the Murphy and Snider groups.

Stereoselective and efficient synthesis of tricyclic guanidine, the key component of batzelladines A and D, was accomplished based on successive 1,3-dipolar cycloadditions and successive cyclizations for the construction of the tricyclic guanidine ring.
