The formation of enolates from oarbonyl compounds by means of strong bases of low 2 nuoleophilioity, such as lithium dialkyl amides, potassium hydride, 3 and others4 has been extensively investigated in reoent years. The reaotions of these anions with electrophiles are

The rapid photoinduced alcoholysis of the octahydrotriborate(l-) anion was observed from the UV irradiation of solutions of (Bu,N)B,H8 and either ethanol or methanol in THF or chloroform. The octahydrotriborate(l-) anion, which is stable to alcoholysis m the ground state, reacts cleanly and rapidl

Diastereomeric 3-O-allyl-4,6-O-benzylidene-2-O-(diphenylphosphatoxy) b-D-glucoand b-D-manno-pyranosyl phenylselenides were prepared and subjected to treatment with tributyltin hydride and AIBN. The gluco-compound undergoes smooth radical cyclization to a single diastereomeric product in high yield w
