If you mean on your product category page: What if you remove (or comment out) the item description from your content-single-product.php, or use CSS – display:none; and place the code in your sidebar.php? Or whatever sidebar template file you are using for your products? If you don’t have one set up, you can do this in you widgets section – create a sidebar. Then go into the php file.
content-single-product.php can be found in: wp-content/plugins/woocommerce/templates/content-single-product.php and the chunk of code you should be moving is:
<div class="summary entry-summary">
<?php
/**
* woocommerce_single_product_summary hook
*
* @hooked woocommerce_template_single_title - 5
* @hooked woocommerce_template_single_rating - 10
* @hooked woocommerce_template_single_price - 10
* @hooked woocommerce_template_single_excerpt - 20
* @hooked woocommerce_template_single_add_to_cart - 30
* @hooked woocommerce_template_single_meta - 40
* @hooked woocommerce_template_single_sharing - 50
*/
do_action( 'woocommerce_single_product_summary' );
?>
