This review describes the methods of preparation and use of 2-(trimethylsiloxy)furan, N-(tert-butoxycarbonyl)-2-(tert-butyldimethylsiloxy)pyrrole, and certain substituted analogues and congeners, including novel 2-(tert-butyldimethylsiloxy)thiophene, to synthesize complex carbohydrates, azasugars, polyhydroxylated alkaloids, C-glycosylated α-amino acids, amino acids bearing quaternary chiral carbon atoms, and thiosugars. Especially emphasized is the preparation of enantiomerically pure compounds of biological interest. Some mechanistic insights are presented.

The aldol-type condensations of the title siloxydienes with chiral electrophilic reagents produce versatile templates to be exploited to synthesize a myriad of multifunctional compounds
