Cinnamaldehyde, reaction with Wittig reagent

ChOLESTANE, 30-METHOXY-, 41, 9 Cholestanol, etherification of, 41, 9 Cholestanyl methyl ether, 41, 9 Cinnamaldehyde, reaction with Wittig reagent, 40,86... [Pg.111]

The reagent is useful because the Wittig reagent (C6H5)3P=CHCHO and the usual phosphonate reagent (C2 H 5 0)2 P OCH 2 C H (O C2 H.-,), do not react with ketones. Moreover, the reaction proceeds stereoselectively to give the trans olefin thus benzaldehyde affords cinnamaldehyde in 11% yield. [Pg.342]

The Ni-catalyzed olefination of aromatic aldehydes and cinnamaldehyde with alkylzinc reagents proceeds smoothly in the presence of MesSiCl [118]. Unlike the Wittig reaction, this reaction achieves high E selectivity. A plausible mechanism consists of three steps the Zn-Ni transmetalation between an alkylzinc and the nickel catalyst, the MesSiCl-mediated addition of the resultant alkylnickel... [Pg.491]

Wittig-type reaction. The reagent reacts with benzaldehyde in liquid ammonia to give a mixture of enynes (2) and (3). Cinnamaldehyde, also expected to give a mix-... [Pg.500]
