This work reports two efficient pathways for the rapid preparation of over 20 structurally diverse BCB ketones, encompassing simple alkyl and aryl derivatives, as well as unprecedented amino acid, dipeptide, bioisostere, and bifunctional linchpin reagents currently inaccessible using literature methods. Analogues are readily forged in two steps and in high yields from simple carboxylic acids or through

Compounds of the form in which Q is selected from -COOH -CH=NR12, -W, -CH2NHR13, -CH=0 and -CH(OR17)2 capable of modulating the activity of histone demethylases (HDMEs), which are useful for prevention and/or treatment of diseases in which genomic dysregulation is involved in the pathogenesis, such as e.g. cancer and formulations and methods of use of such compounds.

Preparation of optically pure aliphatic and allylic amines from amino acids is described. Wittig olefination of α-Boc-amino aldehydes affords Boc-protected allylic amines which can be deprotected to the corresponding chiral unsaturated amines. Catalytic reduction of the Wittig product prior to deprotection affords aliphatic amines of high optical purity.
A general method for the conversion of N-Boc amino acids into their homologated α-hydroxy-β-Fmoc amino acids is described. The protocol involved preparation of the amino aldehyde by reduction of the corresponding Weinreb amides, hydrocyanation, and hydrolysis of the nitrile group, followed by reprotection of the amino acid as the Fmoc derivative. N-Boc amino acid- reduction - hydrocyanation - N-Fmoc
描述了将N -Boc氨基酸转化为其同源的α-羟基-β-Fmoc氨基酸的一般方法。该方案涉及通过还原相应的Weinreb酰胺,氢氰化和腈基水解来制备氨基醛,然后将氨基酸作为Fmoc衍生物重新保护。 N -Boc氨基酸-还原-氢氰化-N -Fmoc氨基酸
