Mesylate

It is used as a catalyst in esterification, dehydration, polymerization and alkylation reactions. Converted by e.g., ihionyl chloride, to melhanesulphonyl chloride (mesyl chloride) which is useful for characterizing alcohols, amines, etc. as melhanesulphonyl (mesyl) derivatives. [Pg.258]

Intramolecular reactions between donor and acceptor centres in fused ring systems provide a general route to bridged polycyclic systems. The cts-decalone mesylate given below contains two d -centres adjacent to the carbonyl function and one a -centre. Treatment of this compound with base leads to reversible enolate formation, and the C-3 carbanion substitutes the mesylate on C-7 (J. Gauthier, 1967 A. Belanger, 1968). [Pg.93]

Alkenylation of cyclopentenone with the alkenylstannane 719 has been used for the introduction of an a,>-chain into a prostaglandin derivative[590]. Even the vinyl mesylate (methanesulfonate) 720 can be used for coupling with alkenylstannanes[59l]. [Pg.235]

The Pd-catalyzed elimination of the mesylate 909 at an anomeric center, although it is a saturated pseudo-halide, under mild conditions is explained by the facile oxidative addition to the mesylate C—O bond, followed by elimination of /3-hydrogen to give the enol ether 910[767],... [Pg.262]

Research conducted by Simons using antiglucocorticoids, including compounds which covalentiy bind to the GR (124), eg, dexamethasone 21-mesylate, has better defined the stmcture and function of the GR. Spiro C-17 oxetanes have shown potent antiglucocorticoid activity in whole cell systems (125,126). [Pg.109]

Mesylated and Tosylated Celluloses. It has been estabUshed that the flame resistance of ceUulose (qv) is improved by oxidation of —CH2OH groups to —COOH (58—60). To correct some of the shortcomings of this treatment, mesyl or tosyl ceUulose was prepared and then the mesyl (CH2SO2) or tosyl (CH2CgH4S02) group was replaced with bromine or iodine (58—60) ... [Pg.487]

The apphcation of bimolecular, nucleophilic substitution (S ) reactions to sucrose sulfonates has led to a number of deoxhalogeno derivatives. Selective displacement reactions of tosyl (79,85), mesyl (86), and tripsyl (84,87) derivatives of sucrose with different nucleophiles have been reported. The order of reactivity of the sulfonate groups in sucrose toward reaction has been found to be 6 > 6 > 4 > 1. ... [Pg.34]

The metal salts of MSA are highly soluble in water as well as in some organic solvents, making MSA usefijl in electroplating operations. For example, lead sulfate is insoluble in water, whereas lead methanesulfonate (lead mesylate) is water soluble. [Pg.154]

Similar alkylations may be effected on oxygen. l-(2-Chloroethyl)imidazolidin-2-one (312) when treated with potassium hydroxide or sodium hydride underwent ring closure to the tetrahydroimidazo[2,l-6]oxazole (313) (57JA5276). This approach can be used for the preparation of bicyclic hydantoins and the corresponding dihydro derivatives of (313) using the mesylate of (312) and NaH (77JHC5U, 79JMC1030). [Pg.139]

A very efficient one-pot procedure for the production of 3-hydroxy-3-cephems (45) has been developed which gives the desired product in almost 80% overall yield from (43a) which is readily available from penicillin. TTie sequence of reactions is (1) mesylation to give (43b), (2) formation of enamine (43c), (3) bromination to afford (44) and (4) hydroly-sis/cyclization with hydrochloric acid in methanol to afford (45) which, in some cases, crystallizes directly from the reaction mixture (B-82MI51000). [Pg.294]
