4-Isopropyl-3-mcthyl

Zur Einfiihrung des Isopropyl-Restes in die 4-Position muB das Knoevenagel-Kondensations-produkt nicht isoliert werden so fiihrt z. B. die Hydrierung von 5-Hydroxy-3-methyl-l-phenyl-lH-pyrazol in Aceton mit Raney-Nickel direkt zu 5-Hydroxy-4-isopropyl-3-mcthyl-l-phenyl-IH-pyrazol (78% Schmp. 114-1150)416. [Pg.537]

In the series of 1-(2,4,6-trial kylphenyl-)3-mcthyl-l//-phospholes (17), only the isopropyl substituted one (17b) entered into reaction with dimeric (pentamethylcy-clopentadienyl)rhodium dichloride to afford Rh(III) complex 74 in a reversible manner. After a careful workup, 74 could be prepared and characterized (Scheme 19). [Pg.165]

In contrast, when a twofold excess of the dialkoxydihydropyrazine is used, then 2 1 adducts are obtained. This has been demonstrated18 by reacting A,7V-bis(2-iodoethyl)-4-methylben-zenesulfonamide with two equivalents of the lithiated D-valine/alanine-based dialkoxydihydropyrazine 8 to give 7V.fV-bis 2-[(2S,57 )-2,5-dihydro-5-isopropyl-3,6-dimethoxy-2-mcthyl-2-pyrazinyl]ethyl -4-methylbenzenesulfonamide (9) in high yield and >95% de. The adduct can be hydrolyzed in high yield to the corresponding amino acid methyl ester 10. [Pg.1049]
