The oxophilicity of silicon allows the efficient protection of a range of hydroxyfunctionalities using either N,Obis(trimethylsilyl)acetamide (BSA) or N,N-bis(trimethylsilyl)urea (BSU). Three distinct mechanistic pathways are proposed for the reactions of the reagents which explain the mild reaction conditions that can be used to achieve a number of important synthetic transformations. The reactions include examples where improved stereochemical control results from the use of BSA.

“…Ruspolinone, norruspolinone and phyllostone were also isolated from Ruspolia hypercrateriformis and Cryptocarya phyllostemon plants. [12][13][14][15] trans-Dendrochrysine was for the first time isolated in 1965 from Dendrobium chrysanthum. [16] Alkaloids dehydrodarlinine and dehydrodarlingianine are found in Darlingia darlingiana tropical tree.…”

This review summarizes the advances in the synthesis of norhygrine and its derivatives over the past ten years, with special attention paid to stereoselective methods of their preparation. Information on the biological activity of some derivatives of 1-(pyrrolidin-2-yl)propan-2-one is presented and the possibility of using pyrrolidines containing a terminal carbonyl group in the synthesis of various alkaloids with useful properties is shown.
