2R-Benzyl-5S-tert-butoxycarbonylamino-4R-(tert-butyldimethylsilanyloxy)-6- phenyl-hexanoic acid, a hydroxyethylene dipeptide isostere corresponding to Phe-Phe, has been synthesized in a practical, stereocontrolled fashion from (L)-phenylalanine.

The first asymmetric synthesis of novel, potent photoreactive γ-secretase inhibitors 2 and 3 has been accomplished. Two Stereoselective methods for the preparation of lactone 9 are described. Protected benzophenone intermediate 19 is prepared via an aldol-elimination reaction followed by a PtO2-catalyzed asymmetric hydrogenation. Two routes leading from 19 to compounds 2 and 3 are evaluated. The application of 3 as an activity-based probe has been demonstrated by localizing γ-secretase activity in the plasma membrane of intact cells.

By two separate routes were prepared four diastereoisomers of (2R or 2S,5R or 5S)-3-benzyl-5-{(1S)-[(tert-butoxycarbonyl)amino]-2-phenylethyl}tetrahydrofuran- 2-ones (11, 12, 17 and 18). Since the furanones were derived from (S)-phenylalanine, absolute co
Stereocontrolled Addition of Propionate Homoenolate Equivalents to Chiral α-Amino Aldehydes
DeCamp, Ann E.,Kawaguchi, Alan T.,Volante, R. P.,Shinkai, Ichiro
, p. 1867 - 1870 (2007/10/02)
A highly efficient route is presented for preparation of the medicinally important hydroxyester and lactone intermediates 1 and 2 from chiral α-amino aldehydes via homoenolate methodology.Several reaction variables were found to influence the ratio of che
