Sjoholm, Asa published the artcileInvestigation of the Lewis acid mediated stereoselective cyclization of cationic aminyl radicals leading to substituted pyrrolidines, Formula: C8H16O2, the publication is Journal of the Chemical Society, Perkin Transactions 1 (2001), 891-899, database is CAplus.
Stereoselective Lewis acid mediated radical cyclizations of variously substituted N-chloropentenylamines afforded the corresponding pyrrolidines with good to excellent diastereoselectivities and in high yields. Several Lewis acids have been screened in an attempt to find an efficient and stereoselective protocol for the formation of pyrrolidines; no apparent correlation between the different Lewis acids and the selectivities obtained was observed
Journal of the Chemical Society, Perkin Transactions 1 published new progress about 5340-78-3. 5340-78-3 belongs to esters-buliding-blocks, auxiliary class Aliphatic Chain, name is Ethyltert-butylacetate, and the molecular formula is C16H24BF4Ir, Formula: C8H16O2.
