93102-05-7 Usage
Preparation
Different sources of media describe the Preparation of 93102-05-7 differently. You can refer to the following data:
1. N-Methoxymethyl-N-(trimethylsilylmethyl)benzylamine is most conveniently prepared by treatment of benzylamine with chloromethyltrimethylsilane followed by formaldehyde and methanol. Access to higher ether homologs is achieved by replacing methanol with the appropriate alcohol. An alternate procedure involves alkylation of lithium N-benzyltrimethylsilymethylamide with methoxymethyl chloride.

Chemical Properties
N-(Methoxymethyl)-N-(trimethylsilylmethyl)benzylamine is clear colorless to light yellow liquid
Physical properties
bp 77–80°C/0.5 mmHg.
Uses
Different sources of media describe the Uses of 93102-05-7 differently. You can refer to the following data:
1. N-(Methoxymethyl)-N-(trimethylsilylmethyl)benzylamine is useful reagent in synthesizing N-benzyl substituted pyrrolidines by [3+2] cycloaddition to α,?unsaturated esters.
2. N-Benzyl-N-(methoxymethyl)-
N-trimethylsilylmethylamine (1) is a valuable reagent for in situ
generation of the N-benzyl azomethine ylide (2). It is generally
preferred over alternative silylmethylamine precursors6–8 because
of ease of handling and use. The ylide (2) is most conveniently
generated from (1) using a catalytic amount of trifluoroacetic acid
as described by Achiwa.Alternative catalysts include LiF,
TBAF,Me3SiOTf–CsF, or Me3SiI–CsF. Mechanistic studies
provide evidence that the reactive intermediate generated from
(1) with either CF3CO2H or F? is a 1,3-dipolar species. Reaction
of (2) with alkenes provides an efficient convergent route
to pyrrolidine derivatives. Alkynes afford 3-pyrrolines which can
be converted into pyrroles.The ylide (2) reacts most readily with
electron deficient alkenes and alkynes since this pairing results in
a narrow dipole HOMO–dipolarophile LUMO energy gap.Examples
of suitable dipolarophiles include unsaturated esters,
ketones, imides,nitriles,and sulfones. Cycloaddition occurs
with complete cis stereospecificity (eq 1) which is consistent
with a concerted mechanism. Dipolarophiles containing
an endocyclic double bond afford fused bicyclic pyrrolidines,
whereas substrates with an exocyclic double bond provide access
to spirocyclic systems.
3. N-Methoxymethyl-N-(trimethylsilylmethyl)benzylamine forms azomethine ylides which readily undergo [3+2] cycloaddition to α,?-unsaturated esters affording N-benzyl substituted pyrrolidines in good yields. It reacts with asymmetric 1,3-dipolar cycloadditions in the practical, large-scale synthesis of chiral pyrrolidines. It is used in the the synthesis of 3-carboxy-1-azabicyclo[2.2.1]heptane derivatives, an important class of physiologically active compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 93102-05-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,1,0 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 93102-05:
(7*9)+(6*3)+(5*1)+(4*0)+(3*2)+(2*0)+(1*5)=97
97 % 10 = 7
So 93102-05-7 is a valid CAS Registry Number.

In this work, two series of cyclic amine-containing benzimidazole carboxamide derivatives were designed and synthesized as potent anticancer agents. PARP1/2 inhibitory activity assays indicated that most of the compounds showed significant activity. The in vitro antiproliferative activity of these compounds was investigated against four human cancer cell lines (MDA-MB-436, MDA-MB-231, MCF-7 and CAPAN-1), and several compounds exhibited strong cytotoxicity to tumor cells. Among them, 2-(1-(4,4-difluorocyclohexyl)piperidin-4-yl)-1H-benzo[d]imidazole-4-carboxamide (17d) was found to be effective PARP1/2 inhibitors (IC50 = 4.30 and 1.58 nM, respectively). In addition, 17d possessed obvious selective antineoplastic activity and noteworthy microsomal metabolic stability. What's more, further studies revealed that 17d was endowed with an excellent ADME profile. These combined results indicated that 17d could be a promising candidate for the treatment of cancer.

A series of benzimidazole carboxamide derivatives have been synthesized and characterized by 1H-NMR, 13C-NMR and HRMS. PARP inhibition assays and cellular proliferation assays have also been carried out. Compounds 5cj and 5cp exhibited potential anticancer activities with IC50 values of about 4 nM against both PARP-1 and PARP-2, similar to the reference drug veliparib. The two compounds also displayed slightly better in vitro cytotoxicities against MDA-MB-436 and CAPAN-1 cell lines than veliparib and olaparib, with values of 17.4 μM and 11.4 μM, 19.8 μM and 15.5 μM, respectively. The structure-activity relationship based on molecular docking was discussed as well.
