✦ Synopsis

The difference between the structure of coriamyrtin I 1) which was elucidated on the basis of the chemical evidences, and the structure of tutin II which was proposed by the X-2) ray crystallography of a-bromoisotutin and Ct-bromoisotutinone, Mathieson, Tetrahedron Letters 1399 (1963). T. Okuda and T. Yoshida, Tetrahedron Letters 2137 (1965); B. M. Craven, Acta Cryst. 17, 396 (1964). == Infrared spectra were measured in mineral oil suspdnsion unless otherwise specified. N.M.R. spectra were obtained on a Varian A-60 spectrometer using tetramethylsilane as internal reference. P. I. Burkhill and J. S. E. Holker, J. Chem. Sot. 4011 (1960). T. Okuda', Pharm. Bull.
