Cobalt catalyzed oxidation of cyclic alkenes with molecular oxygen: Allylic oxidation versus double bond attack

Cobalt (II) Schiff's base complex 1 and 2 exhibit a remarkable chemoselectivity during oxidation of cyclic alkenes with molecular oxygen in the presence of 2-methylpropanal. Catalyst 1 encourages the oxidation of double bond to give epoxide as the major product whereas catalyst 2 promotes mainly the allylic oxidation leading to allylic alcohols or enones.

A Convenient One-pot Hydroboration / Isomerization / Oxidation of Longifolene to Isolongifolol

A convenient one-pot hydroboration / isomerization / oxidation of longifolene (1) to the thermodynamically more stable epimer, isolongifolol (3) is described.Furthermore, a practical in situ method for the hydroboration of 1 in THF, has been optimised to generate the less stable epimer, longifolol (2).
