How to create an Interface for adding dynamic values in an array of objects : Typescript

I have an array and a string which are like:

const array1 = ['id', 'home', 'address']
const string1 = 'isValid'

I want to create an array of objects with some operator(string) in between like the following:

coupon : [
    {
        reference: ['id'],
    },
    '=',
    {
        reference: ['isValid', 'id'],
    },
    'and',
    {
        reference: ['home'],
    },
    '=',
    {
        reference: ['isValid', 'home'],
    },
    'and',
    {
        reference: ['address'],
    },
    '=',
    {
        reference: ['isValid', 'address'],
    },
]

How to create an interface for this, for example if i will add more items in the array1 the array of object will change.

I have created an interface

interface IReference {
    reference: string[]
}

interface IReferences {
    coupon: [IReference, string, IReference] | IReference
}

Now when I add the value of One element which is like shown below, it's not throwing an error.

{
    reference: ['id'],
},
'=',
{
    reference: ['isValid', 'id'],
}

But when i add a string in between 'and'

And then the other elements:

{
    reference: ['home'],
},
'=',
{
    reference: ['isValid', 'home'],
}

It is throwing an error, I think the interface is not correct. How should i achieve this in Typescript with the interfaces?
