The complexes of meso-tetrasubstituted phenylporphyrinwith Yttrium acetylacetonate were prepared by reaction ofY(acac)33H<sub>2</sub>O with H<sub>2</sub>(g)Tpp and
The acetylated glycopyranosyl azideswere obtained inhigh yields with stereoselectivity by phase-transfer catalyzed(PTC)synthesis,and their structures were confirm
