Although useful, this synthesis of reduced quinoxalines has not been fully developed yet. 7-Azabicyclo[4.1.0]heptane (423, R = H) and glycine (424, Q = H) in refluxing aqueous ammonium chloride for 90 min gave octahydro-2(l//)-quinoxalinone (425, Q = R = H) in 40% yield." Similar treatment of 7-methyl-7-azabicyclo[4.1.0]heptane (423, R = Me) gave l-methyloctahydro-2(l//)-quinox-alinone (425, Q = H, R = Me) in 62% yield and 7-methyl-7-azabicyclo[4.1.0] heptane (423, R = Me) with L-alanine (424, R = Me) in refluxing aqueous ammonium chloride for 16 h gave two separable diastereoisomers of 1,3-dimethylocta-hydro-2(l//)-quinoxalinone (425, Q = R = Me), isolated as hydrochlorides in 26%...

Treatment of N-benzoyl-L-alanine with oxalyl chloride, followed by methanolic triethylamine, yields methyl 4-methyl-2-phenyloxazole-5-carboxylate 32 <95CC2335>. a-Keto imidoyl chlorides, obtained from acyl chlorides and ethyl isocyanoacetate, cyclise to 5-ethoxyoxazoles by the action of triethylamine (e.g.. Scheme 8) <96SC1149>. The azetidinone 33 is converted into the oxazole 34 when heated with sodium azide and titanium chloride in acetonitrile <95JHC1409>. Another unusual reaction is the cyclisation of compound 35 to the oxazole 36 on sequential treatment with trifluoroacetic anhydride and methanol <95JFC(75)221>. 

N-Silylated peptide esters are acylated by the acid chloride of N-Cbo-glycine to N-acylated peptide bonds [11]. Likewise, acid chlorides, prepared by treatment of carboxylic acids with oxalyl chloride, react with HMDS 2 at 24°C in CH2CI2 to give Me3SiCl 14 and primary amides in 50-92% yield [12]. Free amino acids such as L-phenylalanine or /5-alanine are silylated by Me2SiCl2 48 in pyridine to 0,N-protected and activated cyclic intermediates, which are not isolated but reacted in situ with three equivalents of benzylamine to give, after 16 h and subsequent chro-...

Alanine, valine, and leucine, (amino-acids with alkyl substituents only) react in a manner very like that of glycine (49—53). All the reactions are rather slow and boiling solutions are normally employed in the preparative reactions. With the cis- and /raws-isomers of Pt(NHs)2Cl2 substitution of the chloride only occurs. Since the tfraws-labilising influence of the incoming groups of the amino-acids is very small, the —NH2 groups remain stable. Consequently chelated complexes are only formed by the amino-acids in the case of the cts-isomer.
