Cyclic tetrapeptide retrohydroxamic acids were prepared as histone deacetylase (HDAC) inhibitors and evaluated the inhibitory activity and found that they have potential as anticancer drugs.
Asymmetric alkylations of a sultam-derived glycine equivalent: Practical preparation of enantiomerically pure α-amino acids

Alkylation of the chiral glycine derivative 2 with 'activated' organohalides under ultrasound-assisted phase-transfer catalysis or with activated and nonactivatcd organohalides in anhydrous medium provides (mostly crystalline) alkylation products 3. Acidic hydrolysis of the pure products 3 gives (aminoacyl)sultams 4 which by mild saponification furnish pure α-amino acids 5 in good overall yields from 2, along with recovered auxiliary 1 (Scheme 1). Pure ω-protected α,ω-diamino acids and α-amino-ω-(hydroxyamino)acids 12-16 are readily accessible from (ω-haloacyl)sultams 3 via reaction with N-nucleophiles followed by acidic and basic hydrolyses (Scheme 2). A reliable determination of the enantiomeric purity of α-amino acids using HPLC analysis of their N-(3,5-dinitrobenzoyl)prolyl derivatives 17 is presented.
