Abstract
![]()
The
base n-BuLi with sparteine allows a kinetic
resolution of N-Boc-2-aryl-4-methylenepiperidines.
The 2,2-disubstituted products and recovered starting materials were
isolated with high enantiomeric ratios. From VT-NMR spectroscopy and
DFT studies, the rate of rotation of the N-Boc group
is fast. Lithiation and trapping of the enantioenriched starting materials
gave 2,2-disubstituted piperidines with retention of stereochemistry.
Functionalization of the 4-methylene group led to a variety of 2,4-disubstituted
piperidines without loss of enantiopurity that could be useful building
blocks for drug discovery.

Abstract
Tailor-made AAs are indispensable components of modern medicinal chemistry and are becoming increasingly prominent in new drugs. In fact, about 30% of small-molecule pharmaceuticals contain residues of tailor-made AAs or structurally related diamines and amino-alcohols. Cyclic tailor-made AAs present a particular value to rational structural design by virtue of their local conformational constraints and are widely used in lead optimization programs. The present review article highlights 34 compounds, all of which are derived from cyclic AAs, representing recently-approved, small-molecule pharmaceuticals as well as promising drug candidates currently in various phases of clinical study. For each compound, the discussion includes the discovery, therapeutic profile and optimized synthesis, with a focus on the preparation of cyclic tailor-made AA as the principal structural feature. The present review article is intended to serve as a reference source for organic, medicinal and process chemists along with other professionals working in the fields of drug design and pharmaceutical discovery.
