We report the X-ray diffraction structure determination of 1,3-di-E-chlorophenyl-2triethylcarbinyl-4-ethyl-5,5-diethyl-l,3-diaza-2,4-diborolidine, II (2a). Previously obtained physical and analytical data on compound II are consistent with the structure formulated as 1,3-di-E-chlorophenyl-2,4-bis(tr

## Abstract Carbonβ13 relaxation times (__T__~1~) and nuclear Overhauser enhancements (Ξ·) have been measured for benzofuran and a series of its methyl derivatives. The contributions of dipolar (__T__~1~ ^DD^) and spin rotation (__T__~1~^SR^) mechanisms have both been determined. The temperature dep
## Abstract Three ganglioside molecular species and a homogeneous ganglioside [GPβ1a (1), GPβ1b (2), GPβ2 (3) and asterinaganglioside A (4)] were obtained from the waterβsoluble lipid fraction of the chloroform/methanol extract of the starfish Asterina pectinifera. On the basis of chemical and spec
