A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 79265-30-8, Name is 2-(Trimethylsilyl)thiazole, molecular formula is C6H11NSSi. In a Article，once mentioned of 79265-30-8, Quality Control of: 2-(Trimethylsilyl)thiazole
The stereochemistry and synthetic utility of the addition of 2-(trimethylsilyl)thiazole (2-TST, 1) to various N-protected alpha-amino aldehydes is described.The reactions of 1 with N-Boc-L-serinal acetonide (2) and N-Boc-L-threoninal acetonide (3) are essential anti diastereoselective (ds = 85-90percent) in agreement with the Felkin-Anh model for asymmetric induction, whereas the reactions with O-benzyl-NH-Boc-L-serinal (4) and NH-Boc-L-phenylalaninal (5) are syn diastereoselective (ds = 80percent).The reversal of diastereoselectivity is interpreted on the basis of a proton-bridged cyclic Cram model for asymmetric induction.Te anti-adduct derived the N-Boc-L-serinal acetonide (2) was subjected to thiazol-to-formyl unmasking to give a one-carbon higher homologue (i. e., the O,N-protected beta-amino-alpha-hydroxy aldehyde 6a).This material serves as a precursor to ribo- and arabino-4-amino-4-deoxypentoses via a further one-carbon-chain elongation with 2-TST and to a C20 sphingosine via Wittig olefination.The above ribo-amino sugar was transformed via sequential Wittig olefination and reduction into a C18 phytosphingosine.
