The Reaction ofN-(Phenylsulfonyl)benzohydrazonoyl Chloride with Enamines

Reaction of heterocyclic enamines with nitrile oxide and nitrilimine precursors.

Alkylidenepyrrolidines 1, 21, 24 and 26 undergo reactions with nitrile oxides and nitrilimines or their precursors to give a range of novel heterocyclic compounds. With alkylidenepyrrolidine ester 1, nitrolic acids give products in which the liberated nitrous acid reacts with the alkylidenepyrrolidine, followed by two cycloadditions to give adducts 3. In contrast, hydroximoyl chlorides give iso...

An Algorithm for the Blind Identification Ofn Independent Signals With

This paper presents a novel procedure for the blind identification of a linear mixture of n sources with 2 sensors. It is shown that the second characteristic function obeys a partial differential equation (PDE) whose coefficients are directly related to the mixture coefficients. A uniqueness result allows the design of an estimation procedure based on this PDE. An algorithm is therefore propos...

On the reliability ofN-body simulations

The general consensus in the N-body community is that statistical results of an ensemble of collisional N-body simulations are accurate, even though individual simulations are not. A way to test this hypothesis is to make a direct comparison of an ensemble of solutions obtained by conventional methods with an ensemble of true solutions. In order to make this possible, we wrote an N-body code ca...

Reaction of L-2-acetylamino-2-carbomethoxyethanesulfonyl chloride with ammonia.

The conversion of L-2-acetylamino-2-carbomethoxyethanesulfonyl chloride (I) to L-2-acetylamino-2-carbomethoxyethanesulfonamide (II) proceeds with considerable variability in yield We therefore investigated the nature of the by-product (s) of this reaction in order to prepare II in consistently high yields and with reproducible physical data. Compound II [m. p. 145°, [a] 54 2 8 ° (c 2, 95% ethan...
