The building block approach to unusual {alpha}-amino acid derivatives and peptides
Article Abstract:
The building block approach was identified as a useful alternative to the commonly used Bucherer-Berg method for the preparation of cyclic unusual {alpha}-amino acid (AAA) derivatives. Preparation of various building blocks containing the AAA moiety and their subsequent utility in the synthesis of a series of unusual AAAs are outlined.

The Emergence of allenamides in organic synthesis
Article Abstract:
Recent studies describing utility of allenamides in stereoselective inter-and-intramolecular synthetic methologies are highlighted. It is observed that nitrogen substituted allenes offer some advantages though chemistry involving other heteroatom-substiuted allenes is of high impact and value.

Titanium-catalyzed enantioselective additions of alkyl groups to aldehydes: mechanistic studies and new concepts in asymmetric catalys
Article Abstract:
An important reaction of the catalytic asymmetric's addition of alkyl group to aldehydes in the enantioselective synthesis of secondary alcohols is discussed. Mechanistic studies with bis(sulfonamide) and BINOL-derived titanium catalysts are summarized.
