The lactone type crown ether mainly adopts the cyclization of acyclic initiator, generally realizes by the acidylate annulation of binary carboxylic acid halides and multiethylene-glycol or dicarboxylate and dihalo multiethylene-glycol.But the reaction of this class often need carried out the intermolecular linear polymerization of ability inhibition in a large amount of solvents, and synthetic agent costliness, process loaded down with trivial details consuming time, environment friendly is poor.Huang Zaifu (Huang Zaifu. the quick novel method of the synthetic crown ether of the synthetic II. tube method of crown compound. organic chemistry, 1985,39:497-501) wait the synthetic lactone type crown ether of employing tube method, though the reaction times is shortened, but still need make thinner with a large amount of benzene.Yet there are no the report of solvent-free synthetic lactone type crown ether.
We embed reaction (the Xia Y M of chain carboxylicesterss such as ethyl acetate with Al-Mg based composite catalyst catalysis epoxy alkane in previous work, Shen Y A, Fang Y, et al.One-step Production ofAlkoxylated Ethyl Acetate with Narrow Adduct Distribution.J of Chem Technologyand Biotechnology, 2006,82 (1): 47-50), but yet there are no the report that epoxy alkane embeds cyclic carboxylic esters.
Summary of the invention
The purpose of this invention is to provide a kind of method of utilizing the synthetic lactone type crown ether of ring expansion single stage method of lactone, be to overcome and have into the deficiency that cyclization becomes technology now, provide a kind of operational path weak point, environmental friendliness, need not thinner, the method that can synthesize the lactone type crown ether fast.
Technical scheme of the present invention: a kind of lactone is through the method for the synthetic lactone type crown ether of ring expansion single stage method, with the lactone is initiator, under 100～200 ℃ and 0.3～3.0MPa condition, make the lactone ring expansion with Al-Mg based compound catalyst catalysis epoxy alkane, single stage method is synthesized the lactone type crown ether;
Lactone and Al-Mg based composite catalyst are added in the potheater, and the add-on of catalyzer is 0.5%～5.0% of lactone and an epoxy alkane reactant total mass, uses N behind the airtight kettle cover
2Displacement gas reactor 3 times, behind reacting by heating thing to 100～200 ℃, drip the epoxy alkane of required adduct number molar weight while stirring, keep pressure at 0.3～3.0MPa, finish reaction after keeping reaction 30～60min after epoxy alkane dropwises again, filtered while hot is removed catalyzer and is made lactone type crown ether product.
The raw material lactone (1) that is adopted, epoxy alkane (2) and institute's synthetic product lactone type crown ether (3) have following structure:
N=1 in the formula～30, R
1=H, CH
3, CH
2CH
3, m=1,2,3, when m=1, R=H or carbonatoms are 1～8 straight chained alkyl; When m=2 or 3, R=H.
Beneficial effect of the present invention:
(1) the present invention directly synthesizes the lactone type crown ether through the ring expansion single stage method by the annular lactone raw material, and the reaction conditions gentleness is simple and efficient, the transformation efficiency height.Can shorten the reaction times greatly, cut down the consumption of energy.
(2) method provided by the invention need not add thinner, and no discharge helps environmental friendliness.
(3) with the ring expansion of Al-Mg based composite catalyst catalysis epoxy alkane to lactone, single stage method is synthesized the lactone type crown ether, and this will provide a kind of novel method for lactone type crown ether synthetic.
