The synthesis of ellacene (1 ,lO-cyclododecanotriquinancene) 2 has been achieved via the Weiss reaction. The regiospecific monoallylation of 6 to provide 7,and the pyrolysis of tris xanthate 11 in HMPA at 22O'C to furnish 2 represent the key steps in the sequence. The HMPA-mediated dehydration of tr

The aldol approach to construct the tetracyclic polyquinane skeleton of l2, followed by hydroboration and the HMPA mediated dehydration of four hydroxyl groups has resulted in the facile synthesis of the chiral polyquinene, tetracyclo[6.6.D.01t5.08\*12]telrddocane-3,6,10,13\_tetraene 2. This method
Easily accessible phenacetyl or benzoyl disulfide proved to be very convenient reagents for a rapid Psulfurttation of phosphfte-triesters and H-phosphonate diesters, respectively. Phosphorothioate (PS) analogues of nucleotides are useful probes to study phosphoryl and nucleotidyl transferring enzyme
