Summary, etc. <p class="Abstract"><span lang="EN-GB">Organocatalytic glycosylation reactions were attempted with an aim to achieve stereoselectivity using chiral TRIP (Binol derived phosphoric acid) and achiral biphenyl phosphoric acids as catalyst and a thiourea derivative as co-catalyst, based on the transition model suggested by Schmidt group<sup>[1]</sup> during co-operative organocatalysis. Though the stereoselectivity as reported by the Schmidt was not observed, but it was found that the thiourea co-catalyst assisted the catalyst in making the reaction faster, especially in the cases where the catalyst was itself not a strong enough acid.</span></p><br /><p> </p>
