Racemicamines and amino alcohols were enzymatically resolved by enantioselectiveacylation using cyanomethyl pent-4-enoate or by enantioselective enzymatic hydrolysis of the dipent-4-enoyl derivatives of amino alcohols to afford chiral pent-4-enamides which can be deacylated chemically to their chiral amines under mild conditions.

[reaction: see text]. Substrates having appendages that pre-encode skeletal information (sigma-elements) can be converted into products having distinct skeletons using a common set of reaction conditions. The sequential use of the Ugi 4CC-IMDA reaction, followed by allylation, hydrolysis, and acylation of a chiral amino alcohol appendage (sigma-element), leads to substrates for a ROM/RCM or RCM reaction
