A new 5,6-dihydro-2H-1,3-oxazine synthesis via Asigner-type condensation
摘要:
In this article - which we dedicate to the lifework1 of Professor Teruaki Mukaiyama - a new general 5,6-dihydro-2H-1,3-oxazine synthesis is described. 3-Hydroxy-2,2-dimethylpropionaldehyde is condensed with a second oxo component and ammonia to the title compound in several examples. In the case of citronellal diastereoselectivity is observed.

The following payer describes the reaction of seven different starting materials for the formation of one product. This reaction is a union of two multicomponent reactions (MCR): the Asinger and the Ugi reaction. The number of possible, highly diverse products of unions of such MCRs is immense.
