Reactions with organozinc reagents

Heterocycles in reactions with organozinc reagents 96MI8. [Pg.210]

In contrast to enone 281, the enantiomers of the corresponding /-butyl-substituted Michael acceptor 284 show different rates and enantioselectivities in their reaction with organozinc reagents and chiral copper catalysts. In all... [Pg.541]

Alkyldesulfurization. Thioglycolic is the leaving group in the Ni-catalyzed reaction with organozinc reagents. [Pg.282]

The 1,2,3-oxathiazinane A,0-ketal 148 undergoes a coupling reaction with organozinc reagent 149 to provide the acetylenic product 150 (Equation 36) <2003JA2028>. A different type of coupling was observed with A)0-ketals 151 and allylsilanes to produce derivatives 152 via the reaction sequence detailed in Equation (37)... [Pg.546]

Ketone olefination occurs on reaction with organozinc reagents in the presence of diphenylphosphite, which causes dehydration of the intermediate alcohol via a... [Pg.27]
