Abstract
ALTHOUGH various investigators1 have prepared benzylideneguanosine, Michelson and Todd are the only ones who report a specific rotation as well as a melting point for this compound. Recently it became desirable to prepare benzylideneguanosine in this laboratory. Using the same general method described previously1, we have obtained a benzylideneguanosine with a melting point in agreement with those already reported, but with a specific rotation which is quite different. On the other hand, benzylideneadenosine has also been prepared and has been found to be identical in physical properties with the substance described by Michelson and Todd1.
