    • Regarding the site of attack by the nucleophile, no specific pattern emerges from the literature. All, 1,2-, 1,4- and 1,6-additions have precedence. In the present case with 1b, it was surprising to note that 1,6-addition occurs at the more hindered of the two positions available. This may be due to the ability of C-3 to accommodate the incipient +ve charge better
