✦ Synopsis

Sulfonamides containing pinacol pro- tected boronate ester groups have been prepared by the addition of H 2 NC 6 H 4 Bpin (pin = O 2 C 2 Me 4 ) to sulfonyl chlorides p-RC 6 H 4 SO 2 Cl (R = CH 3 , NO 2 ). Hydrogenation of the nitro derivatives afford the corresponding sulfanilamides without compromising the aryl-Bpin bond. The sulfanilamides were further functionalized to afford novel platinum complexes containing boranosulfonamides.

## Abstract We have prepared a series of novel 2,3‐dihydro‐4‐pyridones containing boronate esters using the aza Diels–Alder reaction with Danishefsky's diene and imines derived from formylphenylboronic acids. This reaction can be carried out in moderate to high yields using Yb(OTf)~3~ as a Lewis ac
