A novel dimer of trans-anethole has been obtained photochemically. The dimerization proceeds with strict stereospecificity and the structure of the dimer has been ascertained as 1,cis-2-di-p-anisyl-trans-3,trans-4-dimethylcyclobutane. The dimer was transformed into the corresponding diphenol, diacetate and 1,cis-2-dimethyl-trans-3,trans-4-diphenylcyclobutane. The hydrocarbon was independently obtained from β-truxinic acid by reduction. Some dimethyldiphenylcyclobutane isomers have been prepared ...

Corn dextrin preparations with average degradation degrees of 16.7 and 167, or average molecular masses of 2,700 and 27,000, were covalently introduced with 4.5 and 11.2 to 35.4 mol of phosphoric acid, respectively, per mole by dry-heating at 110 to 140°C for 24 h with sodium phosphate, and their effects on cell proliferation and production of immunoglobulin A (IgA) were investigated in C3H/HeN mouse spleen cell cultures. All the phosphorylated dextrin had mitogenic effects and stimulated proliferative ...
