QuestionConformational analysis / selective tosylation, SN2 in decalins
The major products [X] and [Y] formed in the following reactions are
- (a) [X] = OTs on C-3 (less hindered OH), OH on C-2; [Y] = SPh (wedge) replaces the right-ring Br, left-ring Br retained
- (b) [X] = OTs on C-3 (less hindered OH), OH on C-2; [Y] = SPh (wedge) replaces the left-ring Br, right-ring Br retained
- (c) [X] = OTs on C-2 (next to the isopropyl carbon), OH on C-3; [Y] = SPh (wedge) replaces the right-ring Br, left-ring Br retained
- (d) [X] = OTs on C-2 (next to the isopropyl carbon), OH on C-3; [Y] = SPh (wedge) replaces the left-ring Br, right-ring Br retained
