Application

Silicon amine protocol (SLAP) reagents, in conjunction with aldehydes and ketones, form N-unprotected piperazines via photocatalytic cross-coupling with Ir[(ppy)2dtbbpy]PF6 (747769). Heteroaromatic, aromatic, and aliphatic aldehydes are well tolerated, as are structurally and stereochemically complex SLAP reagents. This product was introduced in collaboration with the Bode Research Group and provides a tin-free alternative to SnAP (tin amine protocol) reagents for piperazine synthesis.

Photocatalytic coupling of aldehydes and silicon amine protocol (SLAP) reagents enables the simple, scalable synthesis of substituted morpholines, oxazepanes, thiomorpholines, and thiazepanes under continuous flow conditions. Key to the success of this process is the combination of an inexpensive organic

SLAP Reagents for Piperazine Synthesis

The Bode group has developed SnAP (stannyl amine protocol) reagents that cross-couple with aldehydes and ketones to provide one-step access to a wide variety of saturated N-heterocycles.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
