In another development, Krief has shown that selenoxides (especially aryl/alkyl selenoxides) are capable of replacing amine-oxides as the reoxidant in the dihydroxylation reaction. An asymmetric process based on (DHQD)2PHAL (named SeOAD) was also developed and this gave good to excellent ee s with a range of alkenes." ... [Pg.269]
