2,4,6-Tri-tert-butylpyrimidine (TTBP): A Cost Effective,Readily A vailable Alternative to the Hindered Base 2,6-Di-tert-butylpyridine and its 4-Substituted Derivatives in Glycosylation and Other Reactions

摘要

it is reported that 2,4,6-tri-tert-butylpyrimidine (TTBP),a highly sterically hindered base available through an efficient,cost-effective on epot sequence,is a replacement for 2,6,-di tert-butylpyridine and its 4-substituted analogs in glycosylation reactions and in the formation of vinyl triflates.
