The critical role of stereochemistry in life, medicine, and industry mandates that stereochemistry is well represented in undergraduate lab curricula. This has primarily been achieved via experiments in the enantiomeric resolution of asymmetric acids

Phosphorylation is a very important biochemical process in metabolism and biochemical marking. The mechanism for the biophosphorylation of substrates and the hydrolysis/transesterification of RNA has been suggested to proceed through phosphorane inte

Unlike the hydrocarbon analogs, this first report of enolboration–aldolization of 3,3,3-trifluoropropanoic acid provides essentially pure anti-diastereomers of α-trifluoromethyl-β-hydroxy carboxylic acids in 77–90% yields.

Unlike the reported reversible addition of ketone enolborinates to ketones, the aldolization of ketones with bisboron enediolates derived from carboxylic acids proceeds without difficulty. A variety of α,β,β-trisubstituted-β-hydroxy acids have be

DCC-mediated cyclodehydration of α-trifluoromethyl-β-hydroxy acids provides α-trifluoromethylated β-lactone intermediates, without loss of stereoselectivity. These lactones undergo facile decarboxylation providing a simple route to obtain both al
