A series of α-methylated analogues of the potent sRTX thiourea antagonists were investigated as rTRPV1 ligands in order to examine the effect of α-methylation on receptor activity. The SAR analysis indicated that activity was stereospecific with the (R)-configuration of the newly formed chiral center providing high binding affinity and potent antagonism while the configuration of the C-region was not significant.

A short and general synthesis of enantiomerically pure α-hydroxylated lactone lignans starting from commercially available iPr malate is presented. Key reactions are two stereoselective alkylations of malic acid derivatives. Some enhancements of the alkylation of malic acid esters and a general extension of the alkylation of dioxolanones is reported. Proof of the stereochemical outcome of the alkylation reactions is provided by X-ray diffraction analysis of α-hydroxy-α,β-dibenzyl-γ-butyrolactone, the first crystal structure of an enantiomerically pure α-hydroxylated lactone lignan.
