Kinetic resolution of racemic 2-hydroxy-γ-butyrolactones by asymmetric esterification using diphenylacetic acid with pivalic anhydride and a chiral acyl-transfer catalyst.

Org. Lett. 15(6) , 1170-3, (2013)

Various optically active 2-hydroxy-γ-butyrolactone derivatives are produced via the kinetic resolution of racemic 2-hydroxy-γ-butyrolactones with diphenylacetic acid using pivalic anhydride and (R)-be...

The concept of superactive esters. Could peptide synthesis be improved by inventing superactive esters?

Int. J. Pept. Protein Res. 43 , 312, (1994)

According to the concept presented, esters forming an amide (peptide) bond by the mechanism SN#DN or SN#*DN involving fast decay of the tetrahedral intermediate may behave as 'superactive acylating re...

Observation and elimination of N-acetylation of oligonucleotides prepared using fast-deprotecting phosphoramidites and ultra-mild deprotection.

Bioorg. Med. Chem. Lett. 11(9) , 1105-1107, (2001)

Commercially available 'fast-deprotecting' phosphoramidites are useful for synthesizing oligonucleotides containing alkali-sensitive nucleotides. However, N-acetylated oligonucleotides were observed d...
