I need to have a conditional where clause that operates as so: 

Select *
From Table
If (@booleanResult)
Begin
  Where Column1 = 'value1'
End
Else
Begin
  Where column1 = 'value1' and column2 = 'value2'
End

Any help would be appreciated.

Could you just do the following?

SELECT
    *
FROM
    Table
WHERE
    (@booleanResult = 1
    AND Column1 = 'value1')
OR
    (@booleanResult = 0
    AND Column1 = 'value1'
    AND Column2 = 'value2')
