A solution of 7.2 g of olefin 9 in 100 ml of tetrahydrofuran at 0°was treated with a stream of diborane generated from a solution of 4.75 g of NaBHU in diglyme and 25 ml of BF3-Et20 in 30 ml of diglyme according to the procedure previously used.28 This led to 7.31 g (87%) of a solid which upon crystallization from pentane had mp 165-168°.
