137536-94-8 - Introduction

(4R,5R)-(-)-2,2-dimethyl-α,α,α',α'-tetrakis (1-naphthyl)-1,3-dioxane -4,5-dimethanol is a chiral molecule, also known as NATDM. The following is a description of its nature, use, formulation and safety information:

Nature:
- NATDM is an orange crystal that is soluble in some organic solvents, such as ethers and alcohols.
-It has a chiral center and exists in two stereoisomers:(4R,5R)-(-)-NATDM and (4S,5S)-( )-NATDM.
- NATDM is a disugar alcohol with a naphthyl group. Its chemical structure has four asymmetric carbon atoms.

Use:
- NATDM is an important chiral reagent, which can be used for asymmetric catalytic reactions in organic synthesis.
-It is often used as a chiral ligand to form a chiral catalyst with some metal catalysts, which is used to catalyze asymmetric synthesis reactions.

Preparation Method:
-The preparation of NATDM usually involves a multi-step reaction. One common approach is to synthesize the compound by the addition and reduction of naphthalenone.

Safety Information:
-The specific safety information of NATDM may vary by region and supplier, but in general, it is a toxic substance.
-It may be irritating to human skin and eyes and should be avoided.
-Appropriate protective measures, such as wearing protective gloves, masks and goggles, should be taken when using or handling NATDM.
-During storage and transportation, avoid contact with oxidants, combustibles or strong acids to avoid dangerous reactions.
