5- pheny,amino

The direct sulfonadon of alkylaminotriphenylmethane dyes gives mixtures of substituted products. Although dyes containing anilino or benzylamino groups give more selective substitution, a sulfonated intermediate such as 3[(lV-ethy]-A-pheny]-amino)methy]]benzenesu]fonic acid (ethylbenzylanilinesulfonic acid) is the preferred starting material.

For a facial selective assembly ofthe stereogenic centers and the introduction of the amino functionality, chiral nitrogen-containing reagents, such as benzyl(2-pheny-lethyl)amine (2-19) and trimethylsilyl RAMP derivative 2-24 were applied. Treatment of diacrylates 2-18, 2-21, and 2-23 with 2-19 and 2-24, respectively, gave the protected amino acids 2-20, 2-22, and 2-25 in good yields as single isomers. 

Triazoles (386, R1 = COOMe) were treated with potassium tert-butylate in a mixture of f r/-butanol and benzene for 15-60 min to give (substituted amino)methoxycarbonylmethylenemalonates (387, R1 = COOMe) in 28-54% yields. In the case of the acetyl derivative (386, R = Ph, R1 = COMe), the reaction was carried out in chloroform in the presence of triethylamine at ambient temperature for 8 hr, to give (pheny-lamino)acetylmethylenemalonate (387, R = Ph, R = COMe) in 38% yield. (Phenylamino)acylmethylenemalonates (387, R = Ph,R = COMe, COPh) were also prepared in 62-74% yields when diazo derivatives (388, R1 = COMe, COPh) were heated in benzene for 4-24 hr (80T1821) (Scheme 34).
