Four aminocyclopentanols, as mimics of putative intermediates in the hydrolysis of alpha-d-galactosides, have been synthesized through a number of stereoselective transformations using the cis-fused cyclopentane-1,4-lactone (1R, 5S, 7R, 8R)-7,8-dihydroxy-2-oxabicyclo[3.3.0]oct-3-one as a chiral building block. The compounds were tested towards various

The three-component coupling of Mg acetylides, silyl glyoxylates, and nitroalkenes results in a highly diastereoselective Kuwajima-Reich/vinylogous Michael cascade that provides tetrasubstituted silyloxyallene products. The regio- and diastereoselectivity were studied using DFT calculations. These silyloxyallenes were converted to cyclopentenols and cyclopentitols

Radioiododestannylations was employed to prepare a series of four specifically labeled thienyl alcohols: 1-(5-iodo-2-thienyl)-cyclopentan-1-ol and -cyclohexan-1-ol; 17 alpha-(5-iodo-2-thienyl)-17 beta-estradiol and -estradiol-3-O-methyl ether. The method utilized 5-(trimethylstannyl)thienyl intermediates which had been prepared in good yields from 2,5-bis(trimethylstannyl)thiophene and the appropriate cyclic
