Hi,

[ ] = array of objects { } in Json. 
String jsonStr = '[{"Id":"0015800001PTKzHAAX","Name":"test1" },{"Id":"0015800001PTKxpAAH","Name":"test2"}]';
    JSONParser parser = JSON.createParser(jsonStr);
    while (parser.nextToken() != null) {
        // Start at the array of accounts.
        if (parser.getCurrentToken() == JSONToken.START_ARRAY) {
            while (parser.nextToken() != null) {
                // Advance to the start object marker to
                //  find next account statement object.
                if (parser.getCurrentToken() == JSONToken.START_OBJECT) {
                    // Read entire account object.
                    Account acc = (Account)parser.readValueAs(Account.class);
                    system.debug('Id:' + acc.Id + ' Name:' + acc.Name);
                }
            }
        }
    }

Just replace: Account with  productRenew__c.
