Organozincates reactions

Aspects of the scale-up of aminoalcohol-catalyzed organozinc reactions with aldehydes have been investigated using A lV-diethylnorephedrine as a catalyst.153 In addition to examples with aromatic aldehydes, 3-hexanol was prepared in 80% e.e. [Pg.655]

Organozinc reactions. Barbier alkylation of aldehydes with 2-arenesulfinylallyl halides is highly diastereoselective. Practical conditions for the Reformatsky reaction of aldehydes are further defined. ... [Pg.492]

In less demanding cases where various metals and protocols are comparably satisfactory, the inherent operational simplicity and economy should favor the Sonogashira reaction and the alkynyhnagnesium reaction. In many more demanding cases where these reactions show some difficulties, the organozinc reaction should be considered. [Pg.547]

Organozinc reaction of (537) with crotyl bromide under specific conditions gave an 80% yield of (538), which on reduction with Zn-HOAc yielded a mixture of (539) and (540). Reduction of these enolones with lithium in ammonia using phenol as a proton source gave, after chromatographic separation, a 35% yield of (541), and this was converted in several steps into (542), which is a key intermediate in prostaglandin synthesis. [Pg.270]
