Exo-alkylidene cyclopentane derivatives

Hydroboration of exo-alkylidene cyclopentane derivatives, for example 70, also proceeds smoothly (BH3.THF, 50 °C, 8h) leading to the migration product in the cydopentane ring only and affording the trans alcohol 73 after oxidation of the organoborane 72 obtained by syn migration of the intermediate tertiary organo-borane 71 (Scheme 14) [7-9]. [Pg.424]
