The vibrational deactivation of 102 has been elegantly exploited to achieve highly stereoselective photooxygenation of alkenes in which one site is protected by a nearby C H bond acting as a quencher.146 Replacement of the protective C H group by C D significantly reduces the selectivity of attack. The authors anticipate that this new concept of stereocontrol may prove to be general and may facilitate chiral control in a variety of phototransformations. [Pg.66]
