The molecule is a derivative of the naturally occurring carbohydrate D-fNCtOSe. The data reported here indicate that the ketose six-membered ring is constrained by the presence of two fused five-membered rings into the 3So conformation. These findings agree with the n.m.r.-spectroscopic results for
In the course of recent investigations '-4 in this series, we developed a oneflask synthesis of triacetalated, acyclic aldohexoses by use of 2,2-dialkoxypropanes or l,l-dialkoxycyclohexanes in the presence of p-toluenesulfonic acid. As shown in a preceding paper', one of the triacetals obtained from
