A series of α-thio- and seleno-alkyl-lithiums add to chalcone mainly at the C-3 site in tetrahydrofuran (THF) and quite exclusively at its C-1 site in THF–hexamethylphosphoric triamide; these results contrast with those previously described for other enals and enones.

Addition of dithianes, derived from alkyl- and aryl-aldehydes, to (5R)-menthyloxy-2[5H]-furanone followed by quenching with substituted benzylhalides or a benzaldehyde gives enantiomerically pure lignan type compounds in good yields.
