## Abstract The synthesis and X‐ray analysis of a sulfur dioxide analog of the diuretic agent triamterene, namely 4,7‐diamino‐1‐methyl‐6‐phenylpyrazino[2,3‐__c__][1,2,6]thiadiazine 2,2‐dioxide (2b), is reported. The compound is devoid of the diuretic properties found in other related pyrazino[2,3‐_
tetrathiacyclooctadecane (3) have been obtained by intermolecular cyclization of 1,3-bis(2-bromoethyl)adamantane (4) with thioacetamide using a high-dilution technique. The reaction is concentration-dependent. The crystal structures of 1, 2, and 3 have been determined by single-crystal X-ray diffra
A solvate complex of (-)-1-menthoxygermatrane with chloroform (1) was obtained by reaction of (-)-menthoxytriethylstannane with 1 -bromogermatrane in chloroform. The crystal and molecular structure of 1 was established by X-ray analysis.
