β¦ Synopsis
A new synthetic method has been devised for the rapid conversion of epoxides to chZoro-, bromo-and iodo-hydrins in quantitative yield, under miLd conditions and in the absence of protic acids. In connection with other work on the conversion of epoxides to alkenes', we report in this communication some preliminary results concerning a very simple, high yield, general synthesis of chloro-, bromo-and iodo-hydrins which can be effected in a one-pot treatment of epoxides with triphenylphosphine and the proper halogen in anhydrous dichloromethane at room temperature.

An efficient new method for the synthesis of isonucleosides is described. The key step in the synthesis was the direct coupling of purine and pyrimidine bases with the cyclic sulfate of a carbohydrate intermediate. This reaction proceeded with high regiospecificity and stereospecificity.
