چکیده
Several applications of polystyrene-supported 1,1,3,3-tetramethylguanidine (PS-TMG) in synthetic organic chemistry have been explored. This study evidenced the effectiveness and versatility of this new member of the supported guanidine superbases as an attractive candidate to replace the bases usually employed in organic synthesis during the implementation of environmentally friendly preparative processes.

A novel and convenient chemoselective deprotection method for both silyl and acetyl groups on acidic hydroxyl groups such as phenol and carboxylic acid by using a nitrogen organic base, 1,1,3,3-tetramethylguanidine.
[reaction: see text] 1,1,3,3-Tetramethylguanidine (TMG)(1), a nitrogen organic base, is a convenient and useful reagent for chemoselective deprotection of both silyl and acetyl groups on acidic hydroxyl groups such as phenol and carboxylic acid without affecting aliphatic silyl and acetyl groups. The chemoselectivity is dependent on the acidity of the hydroxyl group.
متن کاملUltrasound-assisted synthesis of 2,4-thiazolidinedione and rhodanine derivatives catalyzed by task-specific ionic liquid: [TMG][Lac]
BACKGROUND Synthesized arylidene derivatives of rhodanine and 2,4-thiazolidiendione have potent pharmacological activities, and these are also key substrates for the preparation of clinically used antidiabetics. FINDINGS Some 1,1,3,3-tetramethylguanidine-based task-specific ionic liquids (TSILs) 1a-1e were prepared and employed to the catalyzed solvent-free Knoevenagel condensation of 2,4-thi...
متن کاملSTUDIES OF TRANSITION METAL COMPLEXES WITH 2N-QUINOLYL- AND 2N-ISOQUINOLYL- 1,1,3,3-TETRAMETHY LGUANIDINES
Ligands derived from 8-quinoline, 6-quinoline, 1 -isoquinoline, and 5-isoquinoline were synthesized. These compounds have been used as ligands for complexation of transition metals, such as copper(II) and nickel(II). According to the spectrosocopic data, copper(II) cation forms (I: 1) and (I:2) complexes with 2-(8-quinoly1)-l,l,3,3- tetramethylguanidine and 2- (I '-isoquinoly1)- 1,1,3,3-tetr...
متن کاملEfficient iron(III)-catalyzed three-component coupling reaction of alkynes, CH2Cl2 and amines to propargylamines.
An iron(III)-catalyzed three-component coupling reaction of alkynes, CH(2)Cl(2) and amines was developed for facile synthesis of propargylamines. Preliminary mechanism investigation using in situ FT-IR reveals that the crucial Fe-acetylide intermediate could be formed through C-H bond activation of alkynes thanks to cooperative effect of FeCl(3) and 1,1,3,3-tetramethylguanidine.
متن کاملDevelopment of antimicrobial coatings by atmospheric pressure plasma using a guanidine-based precursor.
Antimicrobial coatings deposited onto ultra high molecular weight polyethylene (UHMWPE) films were investigated using an atmospheric pressure - plasma enhanced chemical vapor deposition (AP-PECVD) process. Varying concentrations of a guanidine-based liquid precursor, 1,1,3,3-tetramethylguanidine, were used, and different deposition conditions were studied. Attenuated total reflectance - Fourier...
