3-Disubstituted 2-hydroxyalkylthiophenes 9 and 10 were synthesized in a five-step sequence and their diastereoselectivecomplexation with the Cr(CO)3 fragment leading to the corresponding tricarbonyl(thiophene)chromiumcomplexes 11 and 12 was investigated. The diastereoselectivity achieved in the complexation reaction was up to 85% d. e. and depends primarily on the bulkiness of the substituent in the 3-position
