## Abstract Efficient enzyme catalyzed kinetic resolutions of a synthetically useful chiral building block, (__Z__)β4βtriphenylmethoxyβ2,3βepoxybutanβ1βol, are reported. The highest selectivities were achieved by __Lipozyme TL IM__ and __Amano Lipase PS__ enzymes in the presence of vinyl acetate. E
## Abstract 3βMethylβ1,3βpentadiene has been polymerized with the Al(C~2~H~5~)~2~Cl/Nd(OCOC~7~H~15~)~3~/Al[CH~2~CH(CH~3~)~2~]~3~ system to crystalline polymers consisting essentially of cisβ1,4 units (β₯80%). NMR examination has shown that the polymers have an isotactic structure. This conclusion wa
