A FACILE PROCEDURE FOR THE SYNTHESIS OF N-(TOSYL) IMINO-2 ACETIC ACID ESTERS, IMPORTANT ENOPHILES FOR THE DIRECT SYNTHESIS OF EXOTIC ALPHA-AMINOACIDS

Esters of glyoxylic acid and tosylisocyanate react smoothly and afford in a quantitative yield N-tosyl imino-2 acetic acid esters which are key molecules in the ene reaction.

Very High 1,2- and 1,3-Asymmetric Induction in the Reactions of Allylic Boron Compounds with Chiral Imines

The reaction of allyl-9-borabicyclononane (allyl-9-BBN) with chiral imines 3 produced the Cram isomer 4 either exclusively or very predominantly.The very high 1,2-asymmetric induction is explained by a six-membered chairlike transition state, in wh
