diacetate (PIDA)/I2 combination towards Morin 1,4‐thiazine compounds has been developed starting from N,S‐acetals. The latter leads to “one‐step” regioselective methylene insertion without the need for traditional sulfoxide intermediates in good yields. The reaction involves easily accessible N,S‐acetals obtained from cost‐effective basic ketones and cysteamine as starting materials. This process ultimately
